According to BBC, Police have opened a criminal probe into the boyfriend of Whitney Houston’s daughter Bobbi Kristina Brown.
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.
TMZ reported that it was told by multiple sources that police are looking into a “possible altercation” more than an hour before Ms Brown was found.
Despite the couple presenting themselves in public as husband and wife, recent news reports said there are no official documents to show they were ever legally married.
Gordon spent years being raised by Houston in her home and grew up alongside Ms Brown although he was never formally adopted by the singer.
He and Ms Brown revealed their romantic relationship after her mother’s death.
Houston died in February 2012 when she was found in a bathtub at the Beverly Hilton Hotel in Los Angeles on the eve of the Grammy Awards show.
Coroners concluded that the singer died by accidental drowning, with cocaine use and heart disease as contributing factors.
People magazine and other media reported that Ms Brown’s grandmother, gospel singer Cissy Houston, arrived in Atlanta this weekend to be at the hospital.
