A student noticed an item that looked suspicious near the bike racks between the Morrison Center and the student dorms.

BOISE -- A suspicious item on the Boise State campus forced the evacuation of an entire dorm as well as the Morrison Center earlier today.

Around 10 o’clock this morning, a student noticed an item that looked suspicious near the bike racks between the Morrison Center and the student dorms.

That student started a phone chain that ended with the Boise Bomb Squad being called in to take a look.

At the same time students in the dorms woke up to the fire alarm going off.

Keili Bell is one of 300 people evacuated.

"We came outside and there were mobs of people. We were all in our pajamas still and then they were taping off the place,” said Bell. “They told us if we had cars or car keys to take off for a bit."

Lynn Hightower with the Boise Police Department says bomb technicians used a robot to safely remove the item that appeared to be explosive.

Hightower says they later found out that it was not an explosive, but most likely a piece of a Halloween costume left behind.

Students were sent away from the area and over to the Student Union Building where they received more information.

In all it was about 3 hours before students were able to get back inside their dorm.

As a precaution campus security and Boise Police made a campus-wide sweep checking for anything else that may have been connected to this incident, but nothing else was found.

BSU Director of Communications Frank Zang said since this happened on a Saturday morning disruption to the campus was minimal.
