Clarksville police recently arrested a reserve officer with the Ashland City Police Department on suspicion of aggravated domestic assault.

The 43-year-old was reportedly arguing during a visit with his 13-year-old son about a $51 charge on a phone bill, according to an article in The Tennessean.

The newspaper states that according to the arrest warrant, the officer asked his son if the boy wanted him to leave. The boy reportedly said, "Yes."

According to the warrant, the man then pulled his son into a bedroom, took a handgun and put it to the boy's stomach.

The boy reportedly said to his father, "Shoot me. You know it's loaded. Shoot me."

The Ashland police chief reportedly found out about the incident from the Department of Children Services.

The chief then ordered an investigation of the allegations. Afterwards, the man was fired from his position as a reserve officer.

The man was previously an Ashland City firefighter and paramedic. He apparently became a reserve police officer so that if an incident required the SWAT (special weapons and tactics) team, he could quickly be available to help.

The man told a Nashville TV station that the charges against him are false. He said his son made the story up.

"It's shocking to us when there's no evidence to come out, my son can make up something and all this can go out," he told the station.

"The rest of my family was in the house," he said. "No one else heard anything about what he's saying."

The former officer said he believes the charges might be related to a custody battle he's engaged in over the boy with his ex-wife.
