A 12-year-old admitted to making a series of bomb threats to Maryland schools this month and said they did so while knowing that they couldnt be criminally charged under state law because of their young age, police said.

The child, whose identity was not released, emailed seven bomb threats to three Montgomery County schools, just north of the District of Columbia, between Oct. 13 and Oct. 24, the county police chief said Wednesday, the same day his officers responded to two more bomb scares at local schools.

It wasnt immediately clear whether those new threats, at Springbrook High School and Albert Einstein High School, were connected, a police spokesperson told HuffPost.
