AURORA, Colo. -- Students were evacuated from Mrachek Middle School Monday morning after the discovery of a pipe bomb that apparently failed to detonate.

The device appeared to have already been detonated when someone walking near an alcove on the south side of the school saw pieces of it near at trash can about 8:40 a.m., police said.

Further investigation determined that the bomb had not actually gone off, but that someone had burned the object in a failed attempt to set it off. No injuries were reported.

There was surveillance video of a suspect dating back to 6:30 p.m. Saturday, an Aurora Fire Deaprtment official said.

Students were evacuated to the athletic fields so police with K9 units could sweep the building, and then to nearby Rangeview High School to get the students out of the heat. The search wrapped up about 11:30 a.m.

Class was officially canceled just before 11 a.m., said Dianne Lewis of Aurora Public Schools. Parents and guardians of Mrachek students were asked to come pick up their children from Rangeview, 17599 East Iliff Ave., at 12:30 p.m.

School will resume as scheduled Tuesday morning.
