COMMERCE CITY, Colo. Two students have been arrested for allegedly falsely reporting an active shooter and a bomb threat at Adams City High School on Wednesday afternoon, Commerce City Police Department (CCPD) announced Wednesd ay evening. Watch News5's coverage of the incident below:For many, calls of this nature are their worst nightmare. Whether a first responder, a parent, a teacher or a student most will never forget this day, said CCPD Chief Darrel Guadnola in the release. The notion that this call may have been part of a prank is highly disturbing and pulled valuable law enforcement resources away from real emergencies in the Denver metro.The school was placed on lockdown Wednesday afternoon, and hundreds of police officers flooded the building in response to a call about a bomb threat and an active shooter at the school.Police went from room to room to clear the school "believing there may be an active shooter still at large and multiple victims," the release said. They did not find any credible threat or anyone who was injured.As they worked to clear the building, police saw what looked like a trail of blood throughout the school, and later found "two students who were covered in what looked like fake blood the same substance officers had encountered in parts of the building," according to the release. The two students were arrested. In addition to the felony charges for false reports of explosives and an active shooter, the students also face a misdemeanor charge for interference with staff or faculty at an educational facility, the release said.Small also said a student who was inside the school was sleeping at the time police arrived and was surprised and initially not complying with the officers.That student was briefly detained until officers determined he was not connected with the bomb threat. He has been released to a parent."We just appreciate your patience," said Small, when asked about parents' frustration. "We're working with the school district to make sure our messaging is unified. It's a very tenuous situation. We have to be very careful about what we release, because we don't want to scare people unintentionally. Right now, we don't know whether or not this was a perceived or a real threat, but we haven't found anything to indicate that it was a real threat."Scripps News Denver's Kaylee Harter contributed to this web story._______Watch KOAA News5 on your time, anytime with our free streaming app available for your Roku, FireTV, AppleTV and Android TV.
