Police opens up on the detailed account of the family feud between two members of Bobby Brown's family. Contrary to the previous report suggesting that the altercation happened between cousins, it actually involved a mother and a son over a parking ticket.

The mother Tina Brown hit her son Shayne with a bottle, leaving the latter with a bloody head. "Mr. Shayne Brown chose to drive himself to the hospital. Mrs. Tina Brown left the scene before police arrived," a rep for the Atlanta Police Department revealed to Us Weekly.

A cop who responded to the scene said in the police report, "Upon arrival, I spoke with Mr. Shayne Brown whom appeared to have a laceration to the left side of his forehead. Mr. Brown stated that he was attending a party for Bobby Brown's birthday."

"Mr. Brown stated that was in an altercation with his mother about a valet parking ticket. Mr. Brown stated that while arguing with his mother, she spit in his face and hit him on his head with a glass bottle."

The Browns have been in Atlanta to be by Bobbi Kristina Brown's side as she is still fighting for her life in hospital after bathtub drowning. The family recently had a low-key dinner to celebrate Bobby's 46th birthday at Ocean Prime restaurant.

The scuffle occurred at the W. Midtown Atlanta hotel, near the Emory University Hospital where Bobbi remains in a critical condition. Bobby was not present when it happened.
