NIWOT, Colo. (AP) -- Boulder County sheriff's investigators have arrested a 17-year-old Niwot High School student accused of leaving a threatening note at the school.
A message was found in a bathroom stall claiming the school was going to be blown up. Classes were cancelled Friday while the threat was investigated. No explosives were found.
The teen arrested Tuesday is facing charges of false reporting of explosives and interfering with an educational institution. He was not identified and is being held without bond.
