A Brazilian model was badly burned after becoming engulfed in flames following an argument with her girlfriend, disturbing video shows.

Katiuscia Silva Mota, 31, is seen in the shocking footage with her hair and parts of her body ablaze during the Aug. 10 incident at her home in Serra, Brazil.

Security cameras outside Mota’s condominium show the woman appearing to argue with her partner before the pair return inside, where Mota later stumbles out into an entryway on fire. Mota’s girlfriend and several others then come to her aid and try to put out the flames, the clip shows.

The model was left with burns on nearly half of her body after the gruesome incident, Brazilian news outlet G1 reports.

Police in southeastern Brazil are now investigating to see if a crime occurred, according to the report. The model’s mother and her 21-year-old girlfriend, who was accompanied by an attorney, met with police investigators late last week.

Mota’s girlfriend, who works with flammable materials as part of her job in perfumes and colognes, told cops the fire was sparked by a lighter after Mota came in contact with alcohol in their apartment, G1 reports. Mota was also on medication at the time, her girlfriend added.

It is unclear if the fire was sparked intentionally or by accident.

Mota’s mother, meanwhile, said the fire may have been caused by a cigarette, claiming her daughter would not have tried to intentionally set herself on fire due to her profession, the report states.
