Chris Brown's security team has, once again, found itself in hot water. A female fan named Jakaria claims she was hanging out with the pop star and some of his friends when one of Brown's bodyguards allegedly attacked her. 

According to TMZ, the incident happened Sunday at Palms Casino Resort in Las Vegas. The 28-year-old fan told the outlet that everyone hanging out with Brown had to leave their cell phones with security, but when she went to pick up her two phones to leave, security accused her of trying to steal someone else's. 

Jakaria then said one of the bodyguards grabbed her by the hair and threw her to the ground. She also told the site that the guard shook her around so hard she suffered whiplash. 

The fan said she went home after the alleged incident, but eventually called an ambulance when she realized how badly she was injured. It's not clear if the 26-year-old "Liquor" singer was aware of the alleged altercation, but TMZ reported that police are investigating the incident and a battery report was filed. 

This isn't the first time the Brown's team has been accused of manhandling someone. In September, Brown's bodyguards were accused of throwing a woman off his tour bus because she wouldn't give up her cell phone. 

The case was dropped last month when police said the woman didn't have enough evidence, TMZ reported. In 2013, the pop star and his bodyguard Christopher Hollosy were both accused of hitting a man in Washington, D.C. Hollosy said the guy was trying to get on Brown's tour bus, but the alleged victim claimed he was only trying to take a photo with the singer. 

Brown pleaded guilty to misdemeanor assault, while Hollosy was convicted of a similar charge and ordered to complete 24 hours of community service. Hollosy was also placed on probation for a year.
