British comedian Russell Brand has been accused of sexually assaulting an extra on a movie set in a new lawsuit filed in the US.

The anonymous woman referred to as Jane Doe, claims that Brand, who lives in Henley, attacked her in July 2010 on the set of the film Arthur.

The woman claimed the Brand “appeared intoxicated, smelled of alcohol, and was carrying a bottle of vodka on set” adding that he then exposed himself to her in full view of the cast and crew.

The anonymous woman also shared that Brand allegedly followed her into a bathroom later that day and assaulted her as “a member of production crew guarded the door from outside”.

Official court documents share that the anonymous woman "continues to struggle with the resultant trauma”, with her lawyers applying to suppress her identity to minimise the harm she has already suffered.

Her lawyer added that she still works as an actor and “fears retaliation from current and future employers”.

The lawsuit was submitted by New York lawyer Jordan K Merson who also claimed in a restraining order against Brand that his client had “already appeared to be retaliated against for trying to reject Brand’s advances when she was not allowed back on the second and third day of her work assignment”.

Hollywood film studio Warner Bros Pictures and other production companies involved in the movie are also named as defendants, as per the filing.

The anonymous woman is understood to be seeking an unspecified value of damages from Brand, who has always insisted his relationships “were absolutely, always consensual”.

The claims come after Brand strongly denied accusations made by four women in an investigation by The Sunday Times, The Times and Channel 4’s Dispatches.

In the investigation, Brand was accused of rape, multiple sexual assaults and emotional abuse.

The Metropolitan Police are currently investigating multiple sex offence allegations against Brand as the police shared that all allegations are non-recent, and there have been no arrests.
