Authorities say a man was stabbed in the neck with a meat thermometer after asking a woman to silence her cell phone during a screening of the film "Shutter Island" at a Southern California movie theater.

Los Angeles County sheriff's spokesman Steve Whitmore says the stabbing happened Feb. 27 during a screening of the Martin Scorsese film in Lancaster. He says the two suspects remain at large.

Whitmore says the victim had complained about a woman sitting nearby who was talking on her phone during the movie. He says the woman left with two men, but the men returned minutes later and stabbed the victim in the neck.

Two other people in the theater came to the victim's aid and also were hurt. The man was hospitalized with serious injuries.

The sheriff's office says it knew the weapon used was a meat thermometer because the suspects left it behind. No further details were released.
