Rhys Ifans was arrested for allegedly pushing a female security guard at the Comic-Con International festival on Friday (22.07.11).

The Welsh actor - who stars as villainous scientist The Lizard in upcoming superhero movie 'The Amazing Spider-Man' - was being "aggressive and belligerent" at the world famous comic book convention in San Diego, where he was a surprise guest, and he also apparently shoved an official when the guard blocked one of his entourage from entering a backstage area.

In a statement Lieutenant Andra Brown, a spokeswoman for the San Diego Police, said: "He was aggressive and belligerent. He was berating everyone from the security staff to the United States of America. He was cited and released, which is a non-custodial misdemeanour arrest."

The 'Mr. Nice' star - who was celebrating his 44th birthday on the day of the incident - was still allowed to participate in the panel, which also saw his 'Amazing Spider-Man' co-stars Andrew Garfield and Emma Stone, as well as director Marc Webb speak to promote the forthcoming Sony movie, which is based on the Marvel comic book series.

A Sony spokesman said in a statement: "Rhys Ifans was detained by Comic-Con security after a brief incident backstage prior to and immediately following 'The Amazing Spider-Man' panel.

"Police were notified and a citation was issued to Mr. Ifans, who deeply regrets this incident."
