A Knox County couple is suing Knox County, and two sheriff's deputies, alleging the deputies arrested them without cause and used excessive force.
Dash cam video shows officers Jason Acuff and Anthony Rathbone arresting William Holt back in September 2011.
According to court documents, William and Rhonda Holt were stopped for driving without rear lights.
Holt says he was told to sit on the ground and did so, until he saw officers arrest his wife. He says that's when he stood up to find out what was happening, and four to five deputies took him to the ground, tazed him and assaulted him.
Holt says Acuff and Rathbone handcuffed him so tightly he screamed in pain, and suffered permanent injury.
Documents state that the deputies then jerked Holt to his feet and slammed him into the patrol car.
William Holt was charged with driving while intoxicated and Rhonda Holt was charged with public intoxication. Both of those charges were later dropped.
The lawsuit seeks $500 thousand dollars in compensatory damages, and requests a jury trial.
The Holts' attorney says the lawsuit is still in the discovery phase. He says he also has filed a lawsuit against Acuff for a different client, who also alleges excessive force. That incident happened about two months before the Holts' were arrested.
