An 18-year-old man was arrested and accused of making a false bomb threat on Thursday that targeted the Old Mill school campus in Millersville, Anne Arundel County police said.
Matthew Permenter, 18, of Baltimore, was charged with disturbing school operations, threatening to detonate a destructive device and giving a false statement. It could not be immediately determined whether he had obtained a lawyer.
Police spokesman Justin Mulcahy said police received a call from the school at around 8:46 a.m. A current student at the school had said a former student posted an item online that a bomb would be placed near the school and target a "Relay for Life" cancer walk event scheduled to take place on Friday evening.
Mulcahy said police with a K-9 patrol searched the wooded area and the school's perimeter and had come up with nothing as of late morning. Detectives found Permenter at his home.
Anne Arundel schools spokesman Bob Mosier said the campus was not evacuated, and an automated message about the matter was sent to parents.
The school's campus comprises Old Mill Hill High School, Old Mill Middle School North and Old Mill Middle School South, all in one building. Mosier said the total enrollment at all three schools is about 3,750.
