Bobbi Kristina Brown's life may have been in danger long before she was hospitalized. 

In an audio clip of a 911 call obtained by Radar Online, a worrisome neighbor Amy Belton reported "fighting, banging and screaming" coming from Brown and boyfriend Nick Gordon's apartment in October 2012. 

"This has been going on for like four hours," Belton told the dispatcher. "Everything you can think of... they've been fighting, banging, screaming. We just heard one of the girls scream and this huge like thud came." 

Brown has been in a medically-induced coma at Emory University Hospital since she was found face down in a filled bathtub at her Georgia home on Jan. 31.
