Fifty Shades of Grey still
Woman was arrested for public indecency after she was masturbating while watching the film Universal studios

A woman was arrested after apparently getting a little bit too involved in a showing of mummy porn blockbuster Fifty Shades of Grey at a Mexican cinema.

Cinema goers alerted security after allegedly witnessing the 33-year-old pleasuring herself during a screening of EL James' erotic tale at a theatre house in Sinaloa, Mexico.

The woman was removed from the premises and arrested for public indecency, according to local media reports. Authorities did not confirm whether the woman was handcuffed.

The incident is the latest in a series of unsavoury incidents and less than flattering reviews that has greeted the opening of the film. In Glasgow last week three women were arrested after they allegedly assaulted a man who asked them to stop talking during the film.

The film has so far made about $248.7m (£161.6m) at the box office across the world. The biggest opening film ever -- beating even Avatar's total earnings of $241.6m in 2009, which was then dubbed the highest-grossing film of all time.
