A Hillsboro, Oregon, man arrested after playing a violin while naked outside the federal courthouse in Portland last year is suing police.

The Oregonian reports that 25-year-old Matthew T. Mglej claims authorities used excessive force and violated his First Amendment rights. He named the Multnomah County Sheriff's Office and Portland Police Bureau as defendants in a lawsuit filed last week, and he's seeking $1.1 million in damages.

Police showed up after receiving complaints about the demonstration, during which the man played violin, meditated and quoted former Iranian President Mahmoud Ahmadinejad. They said they arrested him for indecent exposure and carried him to a patrol car when he refused to walk.

Mglej claims jail deputies cut his wrists by jerking on his handcuffs and called him names when he cried from the pain and for his service dog.

He has a hearing on the indecent exposure charge next month.
