Trey Songz is the subject of an investigation into an alleged sexual assault allegation in Las Vegas, TMZ reports

The Las Vegas Metropolitan Police Department filed a report on Sunday regarding an incident that allegedly occurred at The Cosmopolitan. It’s still unclear when exactly the alleged assault took place. Songz is said to be cooperating with the investigation. 

A source for The Cosmopolitan told TMZ that Songz and his friends brought a few women back to the hotel after celebrating his 37th birthday at Drai’s Nightclub Saturday night. It is believed that the alleged assault happened sometime afterwards. As of this writing, no arrests have been made. 

The singer has been attached to a number of alleged physical encounters. Songz was reportedly arrested in January during a game at Arrowhead Stadium in Kansas City. He was sued for battery over a 2019 incident where Songz allegedly punched a bartender who was trying to get his attention because he had violated the venue’s policy by standing on the bar. 

Songz was accused in May of bumping a woman’s car and hitting her hand when she exited her vehicle to confront him. She called the police after he fled the scene, and the incident was reported as a hit-and-run. 

A rep for Atlantic has declined to comment in regards to the Las Vegas investigation.
