Known as one of the only places in SF where you can get Cheese on a Stick, SFPD couldn't control the scene San Francisco's Stonestown Galleria this morning. It seems popular 22-year-old British actor Robert Pattinson -- who played Cedric Diggory in the Harry Potter movies, and most notably stars as a humpable vampire in "Twilight" -- caused a mini riot.

In line for today's "Twilight" book signing, one fan was trampled on while waiting to see the star with magical hair, and another "had her nose broken as a result of being crushed up against the front doors to the mall."

Around 200 to 500 teenagers and their families -- some of which had come from as far as Hawaii, Los Angeles and Arizona - were expected to line up for this evening's star sighting. In reality, thousands, it seems, showed up.

Update: SFist reader Melaine reports to us that as of 10 a.m. "there are hundreds of goth teens lined up outside of Hot Topic in Stonestown" -- oh God, please, someone get us a photo of Goths paired with Hot Topic -- "waiting for a twilight book signing, but ... it's been canceled and police have been called in."
