MINNEAPOLIS (AP) _ A man attacked by a police dog while handcuffed during an arrest near Minneapolis has filed a federal lawsuit alleging his constitutional rights were violated and that the officer handling the K-9 was improperly trained.

Reports say Trevor J. Olesen is suing police officer Tom Roddy and the city of Fridley.

The lawsuit says authorities were responding to a reported burglary in May 2016. Jax, a Malinois who'd joined the department the previous year, discovered Olesen inside a dumpster.

Authorities ordered Olesen to come out. Roddy wrote in his police report that he released Jax because he believed Olesen was resisting. The suit says drone footage shows Jax biting Olesen for more than 20 seconds.

Fridley's Director of Public Safety, Brian Weierke, didn't immediately return the Associated Press's call for comment.
