Bomb-sniffing dogs nosed around Boulder High School tonight after a cryptic threat was written in pencil on a boys restroom wall earlier in the day, police said.
“It essentially said a bomb was going to go off at school on Thursday, but it didn’t even say which Thursday,” said Sarah Huntley, a spokeswoman for the Boulder Police Department.
The dogs found nothing after the 6 p.m. search, however.
The school district made a decision to cancel a haunted house on campus scheduled to tonight.
“The school security and police consider this a relatively low-level threat,” Huntley said. “But we’re taking it seriously, because that’s the world we live in. We can’t afford to ignore it and be wrong.”
Notes were sent home with students advising parents of the situation and urging students not to bring backpacks or bags to school Thursday.
The school building will have limited access points, with adults checking students as they enter, Huntley said.
