Bobbi Kristina Brown, the daughter of late singer Whitney Houston, was found unresponsive in a bathtub inside a home in Georgia, police said.
Police in the north Atlanta suburb of Roswell said Brown's husband Nick Gordon and a friend found her Saturday morning. They called 911 and performed CPR because they did not believe she was breathing nor had a pulse, said Officer Lisa Holland, a spokeswoman for the Roswell Police Department.
When police arrived on scene at around 10:25 a.m., officers found her still unresponsive and provided additional care until rescue personnel arrived.
"We don't know if this was a medical condition where she had a problem in the tub or if it was any type of self-initiated or overdose type of situation," Holland said.
Brown was taken alive to North Fulton Hospital, officials said. As of 2 p.m. PT, Roswell police told ABC News that Brown is alive but would not elaborate further on her condition.
Brown was reportedly placed in a medically induced coma, sources close to the family told CNN. Police said the incident remains under investigation.
"Privacy is requested in this matter. Please allow for my family to deal with this matter and give my daughter the love and support she needs at this time," father Bobby Brown said in a statement.
Brown, 21, is the only daughter of Houston and R&B singer Bobby Brown.
Whitney Houston was found dead in a hotel bathtub on Feb. 11, 2012, in Beverly Hills, California. The 48-year-old Houston had struggled for years with cocaine, marijuana and pills, and her behavior had become erratic.
Authorities examining Houston's death found a dozen prescription drug bottles in the hotel suite. They concluded that Houston accidentally drowned. Heart disease and cocaine use were listed as contributing factors in Houston's death.
Brown alluded to the upcoming anniversary of her mother's death on Twitter on Jan. 26.
