Police called to Bobbi Kristina's home week before she was found in tub

Atlanta - One of Bobbi Kristina Brown's neighbours reported a domestic dispute at her address the week before she was found face-down in a bathtub, according to the tape of an emergency call released on Tuesday.

In the call, made on 23 January, a man who identified himself as a security guard at the gated community where Brown lives told a dispatcher that one of Brown's neighbours reported a fight at Brown's address.

The guard said the neighbour reported people "hitting each other and swinging" outside the townhome.

The guard did not give descriptions of how many people were fighting or who they were. The Associated Press requested a copy of the police report and emergency call recording but the materials were not provided.

Brown is the only child of entertainers Bobby Brown and Whitney Houston. She was found face-down in a bathtub at the townhome on 31 January and has been hospitalised in Atlanta since. Police have revealed few details about the circumstances of the case, citing an ongoing investigation.

Three years ago, on 11 February 2012, Houston was found face-down and unresponsive in about a foot of water in a bathtub in the Beverly Hilton hotel just before the Grammys. She later died, and authorities concluded that she had accidentally drowned. Investigators found a dozen prescription drug bottles in the suite and listed heart disease and cocaine use as contributors to her death.

The ongoing investigation and limited details being provided in Bobbi Kristina Brown's case have fuelled speculation about her condition and the circumstances that led to her hospitalisation.

Christopher Brown, Bobby Brown's Boston-based attorney, released a statement on Tuesday railing against several media outlets for publishing "false reports" about Brown's condition and the family's plans for her.

"This is a criminal investigation and the integrity of that process requires silence," Brown said in the statement.

Local news media outlets have reported, without firm attribution, that the investigation is a criminal one. The AP has not been able to independently confirm the reports.
