DUBLIN -- A 14-year-old boy faces intimidation charges after he allegedly phoned in bomb threats to several schools in Helena, Montana, police said.

Helena Police Chief Troy McGee said the boy was arrested Friday. He faces three counts of felony intimidation in Lewis and Clark County Youth Court.

Court records say the boy told investigators he collaborated on the threats with a 16-year-old Helena High student he met while gaming online.

Charging documents say Friday's threat against all Helena schools led to the evacuation of 9,000 students and staff and the cancellation of classes. A threat was made against Capital High School on Monday; two more threats were made against two elementary schools on Wednesday.

Helena police, working with the FBI and the Department of Homeland Security, were able to identify the suspected caller, a 14-year-old boy who lives in Dublin.

Dublin police Lt. Herb Walters said Dublin officers found the teen and took him into custody. The identity of the boy is not being released, pending the ongoing investigation.

No explosives were found.
