Bobbi 's boyfriend on the list

Police have opened a criminal probe into the boyfriend of Whitney Houston's daughter Bobbi Kristina Brown, according to US media reports. News channel CNN and showbiz website TMZ have claimed that an investigation has been launched into Nick Gordon, who reportedly said that he found Brown non-responsive in the bathtub of their home near Atlanta, Georgia. The incident appeared to have eerie echoes of Houston's fatal accidental drowning almost three years ago. Unconfirmed news reports said that Ms Brown, 21, who is in a hospital in Atlanta in a medically induced coma, sustained unexplained injuries prior to the incident on 31 January.
