Lil Twist was named in a battery report after an incident at Justin Bieber's California home on Thursday morning.
Law enforcement sources revealed that the woman who filed the report stated she was hanging out at Bieber's home around 3:30 a.m. Thursday morning when she decided to leave.
Bieber was not at the house but as she tried to exit the residence the woman claims Twist grabbed her by the arm in a forceful manner and tried to prevent her from leaving the home, according to TMZ.
Police are investigating the allegation.
Bieber has previously defended his friendship with 20-year-old rapper Lil Twist after the media speculated that Twist is the reason the Canadian singer has gotten into trouble lately.
Lil Twist, a Young Money rapper who was born Christopher Moore, has been making headlines in mainstream media reports for his friendship with Bieber. "Lil Twist Has Pot-Fueled Party at Justin Bieber's House," a Billboard headline read recently.
"Lil Twist Wrecks Justin Bieber's Fisker -- Then Flees," TMZ reported earlier this month. However, Bieber recently defended his best friend in a Teen Vogue article.
"When I first got signed, I moved to Atlanta and met Twist," Bieber told Teen Vogue. "The funny thing is, I was nobody when we were hanging out. Twist knows me for me."
Still, the 19-year-old pop star said he does not have a large amount of friends.
"Literally, my phone never rings," Bieber told Teen Vogue. "I only have, like, four people that I keep in contact with. I don't need a bunch of close friends to make me happy."
