A Mountlake Terrace High School student was arrested Thursday in connection to bomb threats phoned in to the attendance office last month, according to MTHS Principal Greg Schwab, according to our online news partner the Hawkeye, the MTHS student newspaper.

Mountlake Terrace Police Department detectives arrested the student, who is a minor, in the main office, Schwab confirmed. Schwab also indicated that the bomb threats are considered class B felonies in Washington and that charges are almost certain to be filed.

The student was released to his parents following his arrest, Schwab said.

On Dec. 4, 2014, two phone calls were made to MTHS at 1:26 p.m. The caller said the school was going to blow up in six minutes, forcing an evacuation of the building as well as a police response, according to assistant principal Peter Schurke. Police did not find any suspicious devices when searching the building, Deputy Chief of Police Pete Caw told the Hawkeye.

Schwab said the calls were made using a blocked number. But after Mountlake Terrace police obtained a warrant for the caller’s number, detectives were able to trace the number back to the student’s cell phone, Schwab said.

Edmonds School District spokesperson DJ Jakala said Thursday afternoon the district would be releasing a statement to families Friday and said that the message will include a reminder about the Safe Schools Tip Line. Jakala stressed the importance for people to “step up” and call the line if they have information regarding threats to school safety.
