Police in Concord, N.H., have dropped charges against an 18-year-old man accused of threatening a high school student with a gun after they determined the witness lied.
Police evacuated the school Tuesday night and blocked off streets after receiving a report of a student threatening another student with a weapon. There were night classes and student projects going on at the school.
The Central New Hampshire Special Operations Unit put the school in lock-down and police arrested the teen.
A female student said he pointed a gun at her. She said he was upset with students filming a movie about zombies in the cafeteria because he didn't get a part.
Detectives determined she lied and that the incident didn't happen as reported.
Police planned a 10 a.m. news conference Wednesday.
