Melbourne: Twilight star Bronson Pelletier was attacked by a group of drunken men during a film convention in Birmingham, England.
The 24-year-old Canadian, who plays werewolf tribe member Jared in the film franchise, was left with a broken nose after allegedly being struck, headbutted and put into a headlock.
"Bronson was really angry and upset ... These guys were very nasty. They were so drunk they probably didn``t even realise they were picking on a Hollywood actor," a website quoted a source as saying.
"The convention was full of teenage girls and geeks desperate to see their Twilight heroes so no one expected this sort of trouble," the source said.
Pelleteir, who has starred in New Moon, Eclipse and is in the Breaking Dawn duo of films, was attacked in the toilets.
An organiser of the event at Birmingham``s Hilton Metropole Hotel who tried to intervene was also assaulted.
The four alleged attackers had been attending a wedding reception at the hotel holding the conference and were arrested by police officers. Two men were released and two were bailed in connection with the crime.
A spokesperson for the West Midlands Police Force confirmed that one of the gang was restrained after the deployment of a Taser gun, and all four were eventually arrested on suspicion of assault.
Two were then released without charge, while the other half of the group were granted bail pending further questioning.
