Bobbi Kristina Brown’s medical condition has yet to be revealed, but the Roswell Police Department is investigating. The 21-year-old daughter of Whitney Houston and Bobby Brown was hospitalized Saturday after being found unconscious in a bathtub at her Roswell, Georgia, home. According to TMZ, Brown is now on a ventilator after being placed in a medically induced coma.

“We don’t leave any stone unturned,” Lisa Holland, a spokeswoman for the police department, said in a statement to Us Weekly. “So the police took a search warrant on the home. Before the warrant, initially when the police went into the home there was nothing there that indicated that anything out of the ordinary happened. There [were] no drugs out in the open.”

TMZ broke the news during the weekend after Brown’s husband, Nick Gordon, and a friend, discovered the aspiring starlet unresponsive. Gordon performed CPR on his wife until police arrived and transported her to North Fulton Hospital. Brown’s hospitalization comes almost two years after her mother died at the age of 48. Houston was found submerged in a bathtub at the Beverly Hilton Hotel on Feb. 11, 2012. Her death was attributed to accidental drowning, cocaine and heart disease.

Reports on Bobbi Kristina Brown’s condition are mixed, with TMZ reporting her brain function “significantly diminished.” Police are not revealing any other details.

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

Meanwhile, Bobby Brown asked for privacy in a statement released Sunday. “Please allow for my family to deal with this matter and give my daughter the love and support she needs at this time,” he told E! News.
