Colo. School Cancels Class After Suspicious Persons Scare

A suspicious persons report prompted school officials to cancel classes so police could search Boulder High School with a bomb-sniffing dog, according to the Associated Press.

A cook reported seeing three young men around 6 a.m. today before students or teachers arrived on campus. She said one man wore a mask and two wore camouflage, and all ran away when she yelled at them. She couldn’t describe the men’s faces.

Twelve officers and a K-9 found nothing during an initial search. The results of a second search by a tactical team have not been made available.

It’s not clear whether this was a prank or a serious threat to the school and those on campus. No threats had been received, but school officials and police are taking proceeding cautiously.
