TEWKSBURY (WBZ-AM) -- Police arrested a 14-year-old boy Thursday after they say he threatened to shoot another student.
The teen was charged with threatening the use of a dangerous weapon, two counts of threatening to commit a crime, and disturbing a school assembly.
Middlesex DA Marian Ryan's office said in a release that the student who was threatened reported the teen to school officials around 7:40 a.m., and the high school's resource officer approached the teen.
The school then went into shelter in place mode, and the teen was taken to the Tewksbury Police Station.
He will be arraigned in Lowell Juvenile Court.
Ryan's office said authorities are checking surveillance video and searching the school, but have found no firearms or other threats.
Some parents picked their children up from the school, but the others were moved to areas that police had already cleared for the rest of the school day.
Tewksbury Police will be at the school for the rest of the day.
