Update on Whitney Houston’s Daughter : Police launched investigation after finding she had numerous facial injuries

Police launched an investigation over what caused Whitney Houston’s daughter to fall unconscious in a bath after finding she had numerous facial injuries.

Bobbi Kristina Brown has been in a medically induced coma for 11 days after being underwater for up to 18 minutes.

According to reports in the US, her boyfriend, Nick Gordon, 25, is being questioned by police in Atlanta as to whether he knew anything about the marks on her face.

Investigators have begun taking a closer look at the couple’s relationship after her family expressed concerns she was found with marks around her.

Doctors have told the 21-year-old’s father, singer Bobby Brown, 46, to “prepare for the worst” after saying there was little more they could do.

Wednesday sees the third anniversary of her mother’s death who was also found unconscious in a bath.

The Los Angeles County coroner’s office later confirmed Whitney, 48, passed away as a result of drowning and ‘effects of atherosclerotic heart disease and cocaine use’.
