UPDATE: Police identified the officer as Dorion Young.
A fight between an off-duty Philadelphia Police officer and his teenage son led to a shooting that left the son shot and the officer on desk duty, said police.
The ordeal began around 6:30 p.m. inside the unidentified officer's home on the 2700 block of Taunton Street in Northeast Philly. The duo began arguing with each other and the argument soon turned physical, according to investigators.
"Apparently they got into some sort of scuffle, argument or something," said Philadelphia Police Commissioner Richard Ross.

The off-duty officer was armed with his personal gun during the fight, according to Philadelphia Police Lt. John Stanford.
"During this altercation his weapon was discharged at least twice, striking one of the individuals inside of the home in the torso area of the body," Stanford said.
The victim was taken to Aria Torresdale Hospital where he is currently in critical but stable condition.
The officer's younger son and the gunshot victim's girlfriend were also in the home at the time, said Ross.
Ross said the officer would remain off the street -- he was already recovering from an injury -- as police investigated what Ross called "a police-involved shooting." As of Tuesday morning no charges were filed.
"There are still a lot of questions that need to be answered," said Ross.
The Internal Affairs Unit can't interview the 15th District officer, a veteran of about 20 years on the force, until the district attorney's office can investigate. Northeast Detectives could interview witnesses, however.
Nicholas Mauro, the officer's neighbor, described him as a good person.
"He's a really good guy," Mauro said. "Nice to talk to. Nice personality. I really didn't think any of this would have happened."
