WASHINGTON – Three students were arrested following two separate fights at Paint Branch High School Friday.

Police were called to the Burtonsville, Maryland, school for a report of fighting about 11:20 a.m., a spokeswoman for Montgomery County Police says.

The sequence of events began when security guards tried to stop a fight from starting between two students inside the school’s cafeteria. A young woman who was sitting nearby then attacked one of the guards, police say.

A guard pulled the fire alarm to evacuate the building. The second fight broke out soon after when a police officer barred another student from getting back inside the school.

That student, a 19-year-old man, was arrested for assaulting the police officer.

The young woman, who is legally an adult, and one of the boys fighting in the cafeteria were also arrested. Their names were not released.

Police had previously told WTOP that five people were arrested.
