ATLANTA (AP) – Two members of singer Bobby Brown’s entourage were hospitalized for treatment of knife wounds after a fight at a restaurant early Monday, police said.

Brown, who has a history of drug and alcohol arrests, was apparently not involved, authorities said. He lives outside Atlanta with his wife, singer Whitney Houston.

Brown was at Justin’s Restaurant and Bar performing during a weekly open microphone event. Two members of Brown’s group were either cut or stabbed following a verbal altercation about 1:30 a.m., police Sgt. Kevin Iosty said.

Authorities were looking for the suspects, who drove away. The cause of the fight was not immediately known.

“There was a lot of music and talking going on,” police detective D.L. Dixon said. “It could have been something as simple as a bump, you know, somebody bumped into each other.”

Justin’s Restaurant and Bar is owned by rapper and producer Sean “P. Diddy” Combs.

Shayne Brown, 21, was taken to Piedmont Hospital and Kelsey Brown, 20, was taken to Atlanta Medical Center for treatment, and both were in stable condition Monday, Iosty said. Officials did not know if the victims were related to the singer, but Bobby Brown later visited Shayne Brown at Piedmont Hospital.

Attorney Vincent L. Dimmock said Combs and his entertainment company, Bad Boy Worldwide Entertainment Group, are cooperating with the criminal investigation.

Dimmock, who previously represented Brown when the entertainer was accused of hitting Houston, said he believed Monday was the second time the singer performed at the restaurant’s open-microphone night.

Brown, 36, is the subject of a new eight-episode reality TV show, “Being Bobby Brown,” that will debut June 30 on cable television channel Bravo.

The show will also feature Houston, who has had problems of her own. In March, the 41-year-old singer checked herself into a rehabilitation center for the second time in a year.

Calls to a Bravo spokeswoman and Brown’s publicist were not immediately returned.
