A Tennessee lawman is on the wrong side of the justice system after he was arrested on suspicion of aggravated assault for allegedly threatening his wife and the mechanic with whom he believed she had been having an affair.

According to WSMV, Lt. Derrick Gleaves of the Davidson County Sheriff’s Office is accused of following the mechanic to his wife’s workplace and blocking him in. The unidentified male victim was reportedly returning a vehicle to the female victim.

Gleaves was reportedly in his uniform during the incident, having recently concluded his shift.

He threatened to shoot the mechanic and his wife, according to an affidavit that includes the explicit language he used to imply the two had been having sex. Both denied they were romantically involved, reportedly telling Gleaves they were only friends.

At one point in the altercation, Gleaves allegedly got a handgun from his vehicle and, holding the firearm to his side, told both victims that he should shoot them.

“If you pull a gun, you better use it,” the mechanic reportedly replied.

Police say the suspect left the scene shortly thereafter and no one involved was injured.

The affidavit indicates detectives attempted find Gleaves at his mother’s home, but instead contacted him by phone through his sister.

While he spoke to a detective at that time, he reportedly “refused to come in for an interview, stating ‘press the charges you have to press, but I’m not talking to you without a lawyer.”

Gleaves, who was convicted in 2001 of assault with bodily injury, was put on administrative leave following his arrest. Reports indicate the department will make a decision soon regarding his long-term employment status.
