Police say a cafeteria manager got into a verbal and physical altercation with school administrators around 11:15 a.m. The altercation moved to a cafeteria office — out of view of students — where the manager punched an assistant principal, threw water on him, and then brandished a knife in a threatening manner, according to Arlington County Police Department spokesman Dustin Sternbeck.
Police were called to the school. Upon arrival, the suspect threatened officers, said she had a gun and then reached into a bag, Sternbeck said. The woman was tased by police. No gun was found, but she was in possession of the knife, Sternbeck said.
