BEL AIR, Md. — The Harford County Sheriff’s Office plans to have additional security at five schools after a bomb threat.

The Baltimore Sun reports that a note found at C. Milton Wright High School in Bel Air mentioned the high school and four other schools. Those were public high schools in Aberdeen, Edgewood and Patterson Mill as well as the private John Carroll School. Schools spokeswoman Teri Kranefeld says parents were notified Tuesday night.

C. Milton Wright High School also had an unfounded bomb threat last week.
