Actor Jason Mitchell attends Entertainment Weekly’s Comic-Con Bash held at Float, Hard Rock Hotel San Diego on July 23, 2016 in San Diego, California sponsored by HBO.

*”Straight Outta Compton” star Jason Mitchell is reportedly under investigation for attacking a woman at a Boston hotel.

According to TMZ, an 18-year-old woman claims the actor got rough with her at The Ritz early Monday. According to the police report obtained by website, the woman told police Mitchell grabbed her arms, threw her to the ground by her hair, called her a bitch and then fled.

It all started after the woman tried to crash a party Mitchell was having at the hotel, according to police sources. She grew agitated after being denied entry, and several witnesses say the woman actually struck Mitchell first, with an open hand, according to TMZ.

The police report says other guests could hear the victim screaming for help in the hallway, and The Ritz has since banned Mitchell.

Cops spoke to the actor on scene, but he was not arrested.
