Atlanta police detective D.L. Dixon said that two members of hip-hop and R&B singer Bobby Brown's entourage were hospitalized with knife wounds after an incident at a restaurant owned by rap artist and producer Sean "P. Diddy" Combs early Monday.

The stabbing happened around 1:30 a.m. at Justin's Restaurant and Bar in Atlanta's Buckhead neighborhood, according to Atlanta police detectives.

The popular R&B singer Bobby Brown, known for his blend of R&B and hip-hop rhythms; was at the restaurant performing during a weekly open microphone event when the people he arrived with got into a fight. During the fight, two members of Brown's group were either cut or stabbed, Atlanta police detective Dixon said.

A 21-year-old man was taken to Piedmont Hospital and a 20-year-old man was taken to Atlanta Medical Center for treatment. Both were in stable condition, Dixon said. Brown later visited one of the victims at Piedmont Hospital.

Authorities were looking for the suspects, who drove away after the fight.

It appears Brown, who has had his own brushes with the law in the past, was not involved in the incident, police said. But detectives had not determined what caused the fight, Dixon said.

"There was a lot of music and talking going on," he said. "It could have been something as simple as a bump, you know, somebody bumped into each other."

An attorney for hip-hop mogul Combs said he and his entertainment company, Bad Boy Worldwide Entertainment Group, are cooperating with the criminal investigation.

Attorney Vincent L. Dimmock refused to comment on the stabbing, saying he did not want to interfere with the police investigation. Dimmock previously represented Brown in an unrelated matter.

Monday was the second time Brown performed at the restaurant's open-mic night, Dimmock said.

Brown lives in nearby Alpharetta, north of Atlanta, with his wife, singer Whitney Houston. The stabbing occurred as Brown is promoting a new eight-episode reality TV show, Being Bobby Brown, that will debut June 30 on the cable television channel Bravo.
