A former Chattanooga deputy chief was arrested for driving under the influence on Highway 58 Thursday, according to the Hamilton County Sheriff's Office.

According to an affidavit, 61-year-old Charles Cooke was speeding and driving through red lights on Hickey Valley Road and Highway 58.

A deputy noticed Cooke nearly hitting several vehicles as he was swerving between lanes on Highway 58.

The deputy pulled Cooke over and questioned him.

When Cooke exited the vehicle, the deputy noticed that he was unsteady while standing up, had slurred speech and the smell of alcohol on his breath.

The deputy conducted a sobriety test on Cooke and arrested him for driving under the influence, failure to maintain lane, reckless driving and failure to stop at a red light.

Cooke was a former deputy chief with the Chattanooga Police Department who won over half a million dollars in an age discrimination lawsuit in 2010 after he was demoted and replaced by a younger officer.
