Trey Songz is being investigated for sexual assault.

The Las Vegas Metropolitan Police Department is currently looking into claims of a sexual assault incident that occurred at The Cosmopolitan, reports TMZ. It’s unclear what day the alleged assault occurred, but the police report was filed on Sunday.

On Saturday night, the singer celebrated his 37th birthday at Drai’s Nightclub. A source at the hotel says Trey and his crew brought a group of women back to the hotel from the club before things allegedly took a turn.

Trey is reportedly cooperating with the investigation and no arrests have been made.

This is the latest drama involving the singer. Earlier this year, he was sued for battery by a bartender, who claims Trey punched him in the head during Cardi B’s Fashion Nova launch party in May 2019.

Back in January 2020, Trey was arrested following an altercation with a police officer at an NFL playoff game in Kansas City. However, the prosecution decided not to file charges against him due to insufficient evidence.
