An unarmed man who was attacked twice by a San Diego police dog and shot with multiple bean bag rounds in an incident last month filed a claim Wednesday against the city for injuries he suffered, the first step toward a possible lawsuit.

Attorneys filed a claim with the city of San Diego accusing police of excessive force on behalf of a man bitten by a police dog in Valencia Park.

A man bitten by a police dog during an arrest last month plans to sue the San Diego Police Department, his attorney announced Wednesday. The lawsuit stems from an incident on the night of Oct. 24. The San Diego Police Department said officers were responding to a 911 call about a man who threatened a woman with a gun.
