GREENVILLE, N.C. -- Police in North Carolina are looking for a man who they say fired shots inside a movie theater. 

Greenville police told local media outlets at least one shot was fired into the ceiling of one of the theaters at the AMC Theater late Friday night. Investigators say the shooting stemmed from an argument over seating. No one was hurt, but the theater was evacuated as a precaution.

Police Chief Mark Holtzman told a news conference that officers had detained three people for questioning but determined they were all victims in the incident and were later released. The focus now is on surveillance video from the theater to help police in their investigation.
