BOULDER, Colo. (KKTV) - A terrifying 911 call prompted a rapid response to Boulder High School for a possible active shooter.

“I have listened to this 911 call, it is very scary, in the background of the call you can actually hear shots being fired,” said Boulder Police Chief Maris Herold.

The call came in to the CU-Boulder dispatch center just after 8:30 a.m. It would end up being one of many threats made towards schools across the state Wednesday.

“The caller indicated that he was outside of the high school with a semi-automatic weapon,” Herold said.

Police swarmed the high school campus as they issued a shelter-in-place alert for several surrounding streets precaution.

After sweeping the school, no evidence of a shooter was found.

“This is the scariest type of call you can get especially as you look across the country and see how many of these incidents are happening at schools,” Herold said.

Numerous other schools grappled with similar calls Wednesday, including Canon City High School and Ortega Middle School in Alamosa. None of the reports have been deemed credible.

Local and state law enforcement, as well as the FBI, are investigating.
