A Florida man who served six years in prison for murder was arrested again after he attacked a 16-year-old boy who had fought his son weeks prior, according to police.

Jarrett Garrett McCabe, 47, staked out a bus stop in Lakeland after a neighbor told him that two boys had jumped his son on Monday, the Polk County Sheriff’s Office said.

He was waiting to see if they were going to fight his son again, but when they got off the bus McCabe confronted them, cops said.

McCabe told police that he slapped one of the boys in the face with an open hand. According to a DoorDash driver who witnessed the assault, McCabe punched the boy in the face and twice in the stomach.

Investigators later learned that McCabe’s son had fought one of the teens — the boy McCabe struck — weeks ago and the other, who was with the victim, on Monday. 

But he was not jumped in either scrap, cops said.

The boy who fought McCabe’s son on Monday and his mother spoke with McCabe and the boy apologized to him for fighting with his son after the incident.

“It’s understandable that a dad would be upset about his son getting jumped, but waiting at a bus stop to beat-up a kid is not the kind of example you want to be setting for your child,” Polk County Sheriff Grady Judd said in a statement. “Based on this and his criminal history, he clearly has anger-management issues.” 

McCabe was booked into the Polk County Jail with a charge of simple battery, WFLA reported.

His criminal history includes prior convictions for second-degree murder, aggravated assault with a weapon and for shooting/throwing a deadly missile into a building or vehicle, police said.

He served six years and 11 months in Florida State Prison.
