PUEBLO, Colo. (KKTV) - Operations will be back to normal at a Pueblo middle school Tuesday after an alleged threat was found not credible.
Police were called to Roncalli STEM Academy on Pueblo's southwest side Monday afternoon.
"Officers got here very quickly, began searching the building," said Sgt. Frank Ortega with the Pueblo Police Department.
While police combed the building, the school was placed on lockdown. Students were held past the usual dismissal time and were finally reunited with their parents after 5 p.m.
When asked what the threat was, Ortega said that was something detectives were still sorting out.
"It was kinda ambiguous. ... There's different reports, so that's something that we need to investigate and make the determination of what it was and why we received the call and why we're here.
"... One of the initial reports was that the security guard called it in, so that's another reason for us to have a lot of credibility with the threat. But like I said, there's not an active threat, I want to emphasize that, that way parents don't think something is actually going on."
Nothing suspicious was ever found, and because the campus was deemed safe, district officials said school would be held as normal Tuesday, including the normal amount of security.
11 News has learned this is the second time in six days that a threat has been called in at a District 60 school.
