Actor Brad Pitt was punched in the face Wednesday night while signing autographs at the Hollywood premiere of "Maleficent" starring his partner Angelina Jolie, news reports said.

A man jumped over a barrier outside the El Capitan Theater and attacked the actor at the debut of the film, Los Angeles police sergeant Leonard Calderon said, according to CNN.

CNN said neither Pitt nor Jolie seemed fazed by the altercation.

Police arrested a suspect identified as Vitalii Sediuk, 25, the Los Angeles Times reported.

It said the motive for the attack was not immediately known.

CNN said the alleged assailant could be charged with misdemeanor battery.
