President Michael Sata has suspended Copperbelt Police Commissioner Mary Tembo with immediate effect.
This is according to a statement released by Home Affairs Minister Edgar Lungu.Ms Tembo is alleged to have received a Toyota corolla worth K15 000 from a named mining company for her personal use without declaring it to her superiors.
Mr. Lungu said in view of allegations of corruption levelled against Ms. Tembo,President Sata has with immediate effect suspended her from exercising the powers and functions of her office.
Mr. Lungu said Ms Tembo cannot continue carrying out her duties because the alleged act of converting a motor vehicle or indeed any property donated by well-wishers to personal use without declaring that property to superiors contradicts the code of ethics for the public service.
He said the code of ethics for the public service states that a public service employee shall not accept gifts, rewards or hospitality or receive benefits of any kind from any person or organisation which might compromise or reasonably be seen to compromise one?s personal judgment or integrity.
He said the matter has since been handed over to the Anti-Corruption Commission for investigations.
Mr. Lungu added that President Sata has re-deployed Lusaka Province commissioner, Ms Joyce Kasosa to act during the investigations.

WASHINGTON (AP) ? The Justice Department has charged former National Security Agency contractor Edward Snowden with espionage and theft of government property in the NSA surveillance case.
Snowden, believed to be holed up in Hong Kong, has admitted providing information to the news media about two highly classified NSA surveillance programs.
A one-page criminal complaint unsealed Friday in federal court in Alexandria, Va., says Snowden engaged in unauthorized communication of national defense information and willful communication of classified communications intelligence information. Both are charges under the Espionage Act. Snowden also is charged with theft of government property. All three crimes carry a maximum 10-year prison penalty.
The federal court in the Eastern District of Virginia where the complaint was filed is headquarters for Snowden's former employer, government contractor Booz Allen Hamilton.
The complaint is dated June 14, five days after Snowden's name first surfaced as the leaker of information about the two programs in which the NSA gathered telephone and Internet records to ferret out terror plots.
The complaint is an integral part of the U.S. government's effort to have Snowden extradited from Hong Kong, a process that could turn into a prolonged legal battle. Snowden could contest extradition on grounds of political persecution. In general, the extradition agreement between the U.S. and Hong Kong excepts political offenses from the obligation to turn over a person.
Sen. Bill Nelson, D-Fla., a member of the Senate Armed Services Committee, welcomed the charges. "I've always thought this was a treasonous act," he said in a statement. "I hope Hong Kong's government will take him into custody and extradite him to the U.S."
Michael di Pretoro, a retired 30-year veteran with the FBI who served from 1990 to 1994 as the legal liaison officer at the American consulate in Hong Kong, said "relations between U.S. and Hong Kong law enforcement personnel are historically quite good."
"In my time, I felt the degree of cooperation was outstanding to the extent that I almost felt I was in an FBI field office," said di Pretoro.
The success or failure of any extradition proceeding depends on what the suspect is charged with under U.S. law and how it corresponds to Hong Kong law under the treaty. In order for Hong Kong officials to honor the extradition request, they have to have some applicable statute under their law that corresponds with a violation of U.S. law.
However, Snowden's appeal rights could drag out any extradition proceeding.
Disclosure of the criminal complaint came as President Barack Obama held his first meeting with a privacy and civil liberties board as his intelligence chief sought ways to help Americans understand more about sweeping government surveillance efforts exposed by Snowden.
The five members of the little-known Privacy and Civil Liberties Oversight Board met with Obama for an hour in the White House Situation Room, questioning the president on the two NSA programs that have stoked controversy.
One program collects billions of U.S. phone records. The second gathers audio, video, email, photographic and Internet search usage of foreign nationals overseas, and probably some Americans in the process, who use major providers such as Microsoft, Google, Apple, and Yahoo.

Sometimes, when a remote-control car and a remote-control helicopter love each other very much, they come together and produce something like the B. Well, okay, that's not exactly how this small flying car came about, but it's a nice story. Witold Mielniczek, a computational engineering Ph.D. candidate at the University of Southampton, is currently running a Kickstarter for the simply named B, a hybrid car-helicopter that can handle both challenging terrains and limited air travel. Equipped with a sleek polycarbonate chassis, four propeller driving units (a fancy way of saying wheels) and an HD 1,280 x 720 camera to record one's travels, B seems to be the little flying car that could. In the greater scheme of things, Mielniczek hopes that B will one day be able to operate on water in addition to land and air. While it's no Avengers helicarrier, we suppose every journey begins with a single step. To see B in action, check out the video after the break.

June 21, 2013 ? Researchers at MIT have proposed a new system that combines ferroelectric materials -- the kind often used for data storage -- with graphene, a two-dimensional form of carbon known for its exceptional electronic and mechanical properties. The resulting hybrid technology could eventually lead to computer and data-storage chips that pack more components in a given area and are faster and less power-hungry.
The new system works by controlling waves called surface plasmons. These waves are oscillations of electrons confined at interfaces between materials; in the new system the waves operate at terahertz frequencies. Such frequencies lie between those of far-infrared light and microwave radio transmissions, and are considered ideal for next-generation computing devices.
The findings were reported in a paper in Applied Physics Letters by associate professor of mechanical engineering Nicholas Fang, postdoc Dafei Jin and three others.
The system would provide a new way to construct interconnected devices that use light waves, such as fiber-optic cables and photonic chips, with electronic wires and devices. Currently, such interconnection points often form a bottleneck that slows the transfer of data and adds to the number of components needed.
The team's new system allows waves to be concentrated at much smaller length scales, which could lead to a tenfold gain in the density of components that could be placed in a given area of a chip, Fang says.
The team's initial proof-of-concept device uses a small piece of graphene sandwiched between two layers of the ferroelectric material to make simple, switchable plasmonic waveguides. This work used lithium niobate, but many other such materials could be used, the researchers say.
Light can be confined in these waveguides down to one part in a few hundreds of the free-space wavelength, Jin says, which represents an order-of-magnitude improvement over any comparable waveguide system. "This opens up exciting areas for transmitting and processing optical signals," he says.
Moreover, the work may provide a new way to read and write electronic data into ferroelectric memory devices at very high speed, the MIT researchers say.
Dimitri Basov, a professor of physics at the University of California at San Diego who was not connected with this research, says the MIT team "proposed a very interesting plasmonic structure, suitable for operation in the technologically significant [terahertz] range. ? I am confident that many research groups will try to implement these devices."
Basov cautions, however, "The key issue, as in all of plasmonics, is losses. Losses need to be thoroughly explored and understood."
In addition to Fang and Jin, the research was carried out by graduate student Anshuman Kumar, former postdoc Kin Hung Fung (now at Hong Kong Polytechnic University), and research scientist Jun Xu. It was supported by the National Science Foundation and the Air Force Office of Scientific Research.
