La Mirada~A man was injured last night at the AMC Movie 7 after a fight started inside the theatre when a patron complained about another patron kicking their seat.

The incident occurred around 11:00 p.m. during the 9:50 showing of “Belko Experiment,” a witness told us.

The witness said two couples began arguing in the back of the theatre and a fight ensued. At one point a female allegedly pulled out a “box-cutter” type knife and began stabbing the male victim.

The couple fled the scene and were caught a short time later when, “deputies conducted a traffic stop nearby and arrested the suspects on an assault with a deadly weapon charge,” said Sergeant Jason Cunningham from the Norwalk Sheriff’s Station who confirmed that the seat-kicking seem to spark the incident.

Cunningham said it is unclear whether the weapon used was a box-cutter or an actual knife.

Photos from the scene from a La Mirada Blog Twitter fan, seem to indicate a slash-type wound. WARNING: Graphic photos.

Afterwards, blood could be seen around the auditorium seats as witnesses assisted the victim, who was treated at the scene and released.
