Amid reports that police are investigating injuries found on Bobbi Kristina Brown's body, Radar Online reports that a friend of her boyfriend, Nick Gordon, says the injuries were caused by efforts to revive her when she was found unconscious in the bath tub on Jan. 31.

Documentary producer Daphne Barak, who befriended Brown and Gordon while working on a production last year, said Gordon explained the bruises on Brown's chest in a phone conversation revealing what he told detectives when asked about the injuries.

"Nick told me that the bruises were from his CPR," Barak said.

Domestic violence in Brown and Gordon's relationship was well known among their friends. The reason, according to sources, was Gordon's jealousy of her fame. Sources have said that Gordon "couldn't understand why Whitney's daughter was offered more money than him for a reality TV deal," reports Daily Mail.

A protective order reportedly bars Gordon from being within 200 feet of Brown's aunt, Patricia Houston, who controls the trust which owns the town house he shared with Brown.

Roswell, Georgia, police asked Gordon to not leave Atlanta while they investigate, Barak revealed.

A source close to the Houston family told Radar Online that Gordon has not been allowed in the Atlanta town house where he and Brown lived.

Max Lomas, the man who says he found Brown unconscious in the bath tub, and his lawyers will meet with Fulton County prosecutors in the next two days.

"We have been in contact with Fulton County District Attorney's office trying to arrange a meeting as soon possible," attorney John Petrey told Radar Online Monday.

Currently, no one has been charged or officially named as a suspect in Brown's injuries.
