YMCMB rapper Lil Twist is currently under investigation for allegedly manhandling a woman at Jusitn Bieber's mansion. He was named in a battery report obtained by TMZ in which a woman claims that Twist forcefully grabbed her arm as she was leaving Bieber's mansion around 3:30 am on Thursday morning. 

The woman claims she went straight from the Calabasas home straight to the Sheriff's Department, who is currently investigating the incident. Twist's rep denied claims made by the woman, claiming that she was disruptive at the home and he asked her to leave.

"Lil Twist was not involved in any battery. He asked the guest of a third party at the home to leave, and security escorted the guest from the premises after the guest became disruptive."
