Police were called out to the W Hotel at Colony Square in response to a fight involving Bobby Brown's family.
Police said Shayne Brown was struck in the head with a bottle by Tina Brown.
Shayne Brown received lacerations to his head and drove himself to the hospital.
Tina Brown left the scene before police arrived.
The motive of the fight is unclear.
The Brown family is in town to see Bobbi Kristina Brown, who was found unconscious and face-down in the bathtub of her Roswell home Saturday, nearly three years after her mother was found dead in a bathtub in Beverly Hills.
Authorities said Whitney Houston had drowned and that heart disease and cocaine use were contributing factors.
Bobbi Kristina Brown has been in a medically induced coma since Saturday.
There have been a variety of rumors regarding the condition of Bobbi Kristina Brown. According to TMZ.com, a source close to the family said the claim that Bobbi Kristina Brown was taken off life support is false.
Bobby Brown also released a statement on the rumors:
"If we issued a statement every time the media published a false report regarding this matter, that's all we would be doing 24 hours a day. This is false, just as is the vast majority of the other reporting that is currently taking place."
CBS46.com will have more information as it becomes available.
