A former boxing champion in Atlanta was killed during a robbery early Wednesday morning.

O’Neil Bell, from Jamaica, died after robbers fired one round into his chest, killing him on the streets on Harbin Road, police said.

The retired fighter, nicknamed “Super Nova,” was getting off a MARTA bus at 12:30 a.m. when four thieves swerved by in a stolen 2006 PT Cruiser, Atlanta police Lt. Charles Hampton said during a press conference.

O’Neil Bell was killed in a robbery in Atlanta on Wednesday morning. Police are searching for four men wanted in the shooting.

After an argument between the four-time cruiserweight champion and the four robbers sticking him up, a gunman opened fire, shooting Bell once in the chest, killing him on the spot.

A second victim, who wasn’t related to Bell but on the same bus, was shot in the hip. Responders brought him to Grady Memorial Hospital, where he was in stable condition. The thieves stole the second victim’s bag before escaping in the stolen ride, police said.

Surveillance footage showed the stolen PT Cruiser driving through Atlanta’s streets.

The same car was used for a robbery reported earlier on Tuesday night, Hampton said. The car was stolen at 6:45 a.m. from East Point, an area about 15 minutes south of Atlanta. The car’s owner had his PT Cruiser swiped when he turned the car on and went inside briefly.

Bell was an accomplished boxer and held the WBA, WBC and IBF cruiserweight titles during his 13-year run. He had 29 fights in total, winning 24 of them by knock-out. The undisputed champion retired after his last fight in 2011, defeating Rico Cason with a technical knockout in the first round.
