Bobbi Kristina Brown, Nick Gordon Fight Before Drowning Incident & Coma

Bobbi Kristina Brown allegedly got into a physical altercation with boyfriend, Nick Gordon January 23, days before she was found in her bathtub unresponsive.

According to MediaTakeOut.com, a security guard at the gated community says that neighbors reported that there were people "hitting each other and swinging" outside the 21-year-old's house.

Were the couple Nick Gordon and Bobbi Kristina?

It appears that Bobbi's estranged boyfriend, Nick is being questioned over her current comatose. Bobbi has been in ICU since her January 31 bathtub drowning, and now new reports reveal that a criminal investigation could be open with Gordon as the primary suspect.

According to TMZ, official sources say that the young reality star sustained injuries that may have led to further questioning.

The site says that the couple's mutual friend, Max Lomas arrived at their home around 9 AM and was entertained by Nick until he wandered off. Lomas says the cable guy arrived around 10 AM and needed access to the couple's master bedroom and that when Kristina was discovered face down in her tub. Reports claim Lomas screamed for Nick- who rushed in and started performing CPR.

TMZ reported, Lomas claims that Nick cleaned up blood stains in the home and now has lawyered up following further investigation.

KTLA 5 reporter, Nerissa Knight reported that friend of the family admitted that, "Bobbi Kristina and her husband Nick were having marital problems and that he reportedly moved out last week to live with somebody else. There are also reports that he has been banned from the hospital by the family, but the family has not commented on that."

Since then, Bobbi has been placed in a medically induced coma after she was found face down in her bathtub Saturday, January 31. Bobbi Kristina was discovered unconscious in her bathtub by her husband, Nick and their friend. Sources say the young celebrity is breathing with a ventilator machine and further tests haven't shown any progress.

Doctors say she has lost a lot of brain activity. Whitney fans were in shocked after hearing the news since the "Bodyguard" actress was found dead in her bathtub at the Beverly Hilton hotel 2012.
