More details have emerged on the critical condition on Bobbi Kristina Brown, who was found unconscious in the bathtub of her Roswell, Georgia home on Saturday, Jan. 31. Lisa Holland of the Roswell Police Department confirmed to Us Weekly that the 21-year-old daughter of Bobby Brown and the late Whitney Houston was found facedown in the bathtub. 

"I can’t comment on her condition because of medical privacy laws," Holland tells Us. "I know she is alive and the only thing they would notify me of is if her condition changed."

Holland revealed that the 911 call was made at 10:20 a.m. ET on Jan. 31, by a friend named Max. When police arrived, Brown's husband Nick Gordon was performing CPR, which an officer then took over. 

Brown was transported to North Fulton Hospital, where TMZ reported she was placed in a medically induced coma. 

Back at her home, police continued investigating for signs of foul play or drugs. 

"We don't leave any stone unturned," Holland said of the procedure. "So the police took a search warrant on the home. Before the warrant, initially when the police went into the home there were nothing there that indicated that anything out of the ordinary happened. There were no drugs out in the open." 

Almost three years ago, Brown's mother Whitney Houston was found dead in the bathtub of her Beverly Hills Hotel on Feb. 11, 2012.
