A Virginia man has filed a lawsuit accusing a group of D.C. police officers of unlawfully detaining him for taking pictures of them conducting a traffic stop.

In a lawsuit filed Thursday in federal court in Washington, Jerome Vorus says police ordered him to stop taking pictures of them in Georgetown in 2010. Vorus says police took and held his identification for 30 minutes after they saw him photographing though he was never arrested.

He’s asking for a ruling that individuals have a right to take photographs and video of law enforcement officials as long as the person doesn’t physically interfere with law enforcement operations, as well as an unspecified compensatory and punitive damages.

Vorus is being represented by lawyers for the Washington chapter of the American Civil Liberties Union.
