For the second day in a row, security fears disrupted classes at Woodland Park High School Thursday (2/13/14).
Woodland Park School District RE-2 says that a ticking sound was heard coming from a student's backpack at about 8 a.m.
Police were already at the school because of Wednesday's lockdown. The decision was made to evacuate students in the wing of the school were the backpack was found to another part of the building.
Nearby Gateway Elementary was placed on secure perimeter for a couple of minutes while police investigated the ticking backpack.
Police opened up the backpack and found a metronome inside, according to the district. Musicians use metronomes to track tempo and timing when they play.
The school district says that by 8:25 a.m. all students were back in class.
