"Chasing Time" crooner Azealia Banks is facing investigation after she purportedly pounded a security guard who was about to kick her out of the club due to unruly behavior.

According to a report by TMZ, the singer was partying at Break Room 86 late last month and showed some nasty behavior that prompted the security to ask her to leave as well as her friends. However, instead of obliging, the 24-year-old rapper attempted to ring the fire alarm. And when she was halted by the guard, Banks laid her hands on him and assaulted the beefy bouncer.

By the moment Banks jumped to the security and pounded him, her friends immediately tried to pull the rapper off the bouncer. Although her friends tried to halt her a lot of times, Banks just continued attacking the bouncer until another security break into the brawl and stopped Banks from her assault.

Banks' assault news comes a day after her first U.S. tour for her latest album, "Broke With Expensive Taste," was canceled. As Pitchfork shares, the "Ice Princess" singer has yet again rescheduled her tour due to being "very busy at work." Originally, Banks' tour was supposed to roll in August. However, it was rescheduled for November since her co-liner, K. Michelle, has dropped out the gig.

Months before, Banks also entered a scuffle, which was also caught in camera, after bombing a flight attendant with a homophobic slur. TMZ shared in September that the rapper ranted during a Delta Airlines flight from New York to Los Angeles and called out the employee as a "f----ng f---ot" as she is about to descend off the plane.

During the flight, it was not only the employee who was attacked by Banks, but also a French man who received a spit in the face from the rapper.

Banks' unruly behavior was said to have caused by the French couple who blocked her way out while they were pulling their bags off the overhead bin. As told by TMZ's eyewitness, Banks "tried to squeeze by the couple when the French man put his hand out" and that's when Banks reportedly "went nuts." Aside from spitting on the man's face, she allegedly "punched him in the face and clawed at his shirt."

The French couple let Banks' assault pass since they said they are on a holiday and they don't want any hassle. Currently, with regard to Banks' latest assault, she is held under investigation by the Los Angeles Police Department for criminal battery.
