Bobbi Kristina Brown's aunt claims Nick Gordon is ''under investigation for attempted murder''.
Leolah Brown has criticised American TV star Dr. Phil for allowing the 25-year-old partner of Bobbi to appear on 'The Dr. Phil Show', suggesting his interview on the programme interfered with police investigations following the 22 year old's submission to hospital in January.
Writing on Facebook, she said: ''Nick Gordon is under investigation for the attempted murder of my niece Bobbi Kristina Brown.
''We have strong evidence of foul play. Until this investigation is completed by law enforcement, I would ask that you or anyone else not provide this individual a platform to spin this situation to his benefit.
''If Nick Gordon does not have the courage to speak with my brother Bobby Brown and/or law enforcement about what happened the day my niece's body was found in a bathtub, he does not deserve to have a platform to speak to anyone of your caliber until this investigation is concluded.''
The daughter of the late Whitney Houston was discovered face down in a bathtub at her home in Georgia on January 31 and has remained in hospital ever since, with police confirming they are investigating the incident.
Meanwhile, Bobbi's pal and former housemate Steven Stepho claims Nick - who has been banned from visiting his partner in hospital - used Krissi for her mother's inheritance, and was frequently violent towards her.
He told The Sun newspaper: ''When Whitney died Nick was left with nothing, so he knew he had to control Krissi to get access to the money.
''She'd do whatever he told her. He was very manipulative and would even use the drugs to control her.
''They would argue a lot and there were times when he would be violent with her and push her around.''
