Wendell Pierce, the actor known for his performance in HBO’s “The Wire,” was arrested on Sunday for allegedly attacking a female supporter of Democratic presidential hopeful Bernie Sanders outside an Atlanta Hotel.

The incident in which the actor purportedly grabbed a woman’s hair and smacked her head for supporting Sanders happened while he was in Atlanta for a movie shoot. Pierce, 52, was arrested outside the Loews Hotel at 3:30 a.m., the Mail Online reported.

The actor, popular for his role as Detective Bunk Moreland in “The Wire,” has been charged with battery.

“The incident did not rise to anything significant so no special notification was made … it was treated like any other arrest a patrol officer conducts,” Atlanta police spokesman Donald Hannah said in a public statement as quoted by Mail Online. “Mr. Pierce made no indication he was famous nor did the officer inquire,” an officer said.

Pierce was having a casual conversation with the other two guests at the hotel but as the topic on Sanders was raised, the conversations turned serious. Pierce, who is a supporter of Democratic frontrunner Hillary Clinton, assaulted the woman and her boyfriend following a heated up discussion.

The alleged incident took place in The Lobby, which is an open bar located between the guest check-in desk and the restaurant, the Daily Beast reported.

According to the couple, Wendell Pierce became angry when the woman declared their support for the Vermont senator. He allegedly pushed the woman’s boyfriend and went after her “grabbing her hair and smacking her in the head.” Some witnesses disputed the claims by the couple, saying the woman had stepped into an altercation already underway.

The hotel security was alerted after a short while. The Atlanta Police Department was called in following the protocol. Pierce was released after posting a bond of US$1,000 (AU$1,370).
