Exclusive: U.S. government, police working on counter-drone system - sources

As concerns rise about a security menace posed by rogue drone flights, U.S. government agencies are working with state and local police forces to develop high-tech systems to protect vulnerable sites, according to sources familiar with the matter.

Although the research aimed at tracking and disabling drones is at an early stage, there has been at least one field test.

Last New Year's Eve, New York police used a microwave-based system to try to track a commercially available drone at a packed Times Square and send it back to its operator, according to one source involved in the test.
