Two relatives of Bobbi Kristina Brown got in a fight early Friday at an Atlanta hotel, police said.

Shayne Brown, a cousin of pop star Bobby Brown, took himself to the hospital after Tina Brown, Bobby Brown’s sister, hit him with a bottle, Atlanta police told NBC News. Tina Brown left the scene before police got there, they said.

The nature of the fight was not clear.

Bobbi Kristina Brown, 21, the daughter of Bobby Brown and the late pop diva Whitney Houston, was found face down in a bathtub last week. She was put in a medically induced coma and has been on a ventilator, family and friends have said.
