Police say a suburban Philadelphia high school was briefly locked down after school security mistook a student’s umbrella for a gun.
Authorities say Upper Dublin High School was locked down Monday morning after four male students were spotted on a school security video.
School officials were able to identify one of the students and police quickly located all four students, who were being interviewed.
Monday marks the first full day of classes for most students since 20 children were killed in a shooting at Connecticut elementary school.
An Upper Dublin student said he was herded from the gym into a locker room until the situation was resolved. The sophomore says it makes sense to be alert given Friday’s shooting in Newtown, Conn.
