Busta Rhymes Busta Rhymes

Busta Rhymes was arrested Wednesday night and charged with assault, the New York Daily News reports. The weapon in question? A protein shake.

The 43-year-old rapper was taken into custody around 8:30 p.m. at a gym in Manhattan's Chelsea neighborhood after getting into a dispute with an employee there, according to the Daily News. He reportedly threw a 17-ounce cardboard container of a strawberry protein drink at the employee's head.

It's unclear what the altercation was about, but witnesses told police that this isn't the first time the two have clashed, and that Rhymes had been asked to leave the gym after approaching the front desk to buy a drink. A previous argument between Rhymes and the gym employee occurred when the employee refused to let Rhymes bring a cameraman into the gym to film his workout.
