It has been reported that a criminal investigation has been launched into the boyfriend of Whitney Houston's daughter.
Nick Gordon claims he found Bobbi Kristina Brown unconscious in a bathtub at her home near Atlanta, Georgia last weekend.
CNN reports that in another development it is also believed Whitney's daughter sustained unexplained injuries prior to being discovered.
Authorities investigating the incident are reportedly suspicious because she was found face down.
Bobbi Kristina Brown is currently in hospital in a medically induced coma. However there are conflicting reports as to whether she has been taken off life support or declared brain dead.
The reports follow the release of a 911 call of the moment two members of Bobby Brown's family got into a fight at his birthday party in Atlanta, where his daughter Bobbi Kristina (21) is in hospital fighting for her life.
Police were called to Atlanta's W Hotel early on Friday after one of the R&B singer's relatives smashed her son over the head with a glass bottle.
Shayne Brown said his mother, Tina Brown, spat on him before striking him with the bottle during an argument about a valet parking ticket, a police report said.
The fight happened at a party to celebrate Bobby Brown's 46th birthday on Thursday - five days after Bobbi Kristina was found unresponsive face down in a bath tub.
In the call, a witness said eight to 10 people were fighting at the hotel bar. He told police one person had "used one of the glasses at the bar as a weapon".
"They hit somebody and cut them in the face," he said. Police did not say how the pair are related to the singer.
Shayne Brown suffered cuts and drove himself to the hospital, while Tina Brown left the hotel before police arrived. No charges have been filed.
Meanwhile Bobbi Kristina Brown's family have denied reports she is brain dead or has been taken off life support.
However her cousin has said "doctors see no hope".
Posting on Instagram as yfkennedy, Jerod Brown wrote: "Though it seems the odds are against her, though doctors don't see any hope for change… though it looks impossible for her to stand again STILL PRAY FOR BK."
Houston (48), a six-time Grammy Award winner and actress who battled substance abuse, died in February 2012 after she, like her daughter, was found unresponsive in a bathtub.
Authorities found a dozen prescription drug bottles in Houson's Beverly Hills Hotel suite and concluded that she accidentally drowned - although heart disease and cocaine use were listed as contributing factors.
