DENVER — The Denver Police Department is facing another federal lawsuit for excessive force.

Civil rights attorney David Lane filed a suit in federal court on Thursday on behalf of Barry Castille.

Castille said he was roughed up and injured by officers when he pulled up to his home to find police investigating a shooting in his front yard.

His son recorded the incident on his cellphone. In the recording, Castille can be heard asking officers why he is being arrested and yelling at them to stop hurting him because of his disability.

“Sir, I’ve been through a surgery. … Stop pulling. I can’t bend my arms back. … Look at my neck. I can’t bend my arms. I’ve been through a spinal surgery. I can’t bend my arm back,” Castille is heard telling officers.

The incident happened in April 2015 outside the 56-year old’s home near East 33rd Avenue and Holly Street.

On Friday, Castille sat in Lane’s office to speak about the night he says changed his family’s life.

“I was jumped on and abused by the Denver Police Department. That threw my shoulder, my body out of whack. Not able to provide for my family,” he said.

Castille said his wife had called 911 to report the shooting when the victim ended on their front porch.

“I was yanked out the car. He telling me he would shoot me,” Castille said.

Castille said his degenerative spinal condition makes his movements slow and his body weak. He said police didn’t listen to him about his disability despite his repeated pleas for them to stop.

“They had twisted and toss every which way,” he said.

Castille ended up in the back of a squad car for more than an hour. His shoulder was dislocated when he was handcuffed and he said officers denied him medical aid.

Lane said investigators then illegally searched Castille’s home.

“Its not just about me. It’s about other disabled people being treated the way I’m being treated,” he said.

Castille was charged for disobedience to a police officer. Those charges were dropped.

In an email, the police department said it has not yet been formally notified of the lawsuit. It asked that the public reserve judgment until all the facts of the case are available.
