Tenn Police Under Fire After Video Goes Viral Of Them Beating Black Man Inside His Home After Refusing To Pull Over For Them

A Black man who says he was beaten by Oakland, Tennessee, police following a traffic stop attempt told ABC News he is traumatized following the incident.

"Looking back on the videos and the pictures, I realized I was really knocked out," said Brandon Calloway in an interview. "It is kind of hard to watch. But it is fulfilling that, to know that it was on video."

Calloway’s attorney, Andre Wharton, says officers with the Oakland Police Department used excessive force when they allegedly beat Calloway with a baton and used a stun gun on him after a July 16 traffic stop.

The Tennessee Bureau of Investigation (TBI) is investigating the incident at the request of 25th Judicial District Attorney General Mark Davidson, the agency said. Several documents concerning the case, including body camera footage, remain confidential, TBI told ABC News.

According to an affidavit acquired by ABC affiliate WATN, officers followed Calloway to his home after he allegedly refused to stop for police. Officers say they tried to stop Calloway after he allegedly ran a stop sign and was going 12 mph over the speed limit. Calloway was going 32 miles per hour when the speed limit was 20, the affidavit says, according to WATN.

Police say the officers tried to stop Calloway, but he refused to stop and instead drove to his home and ran inside.
