Here's an update:

ROMEOVILLE - Hermansen Elementary School's classes were cancelled Friday, after what turned out to be a harmless device, was discovered taped to a light pole in the school's parking lot.

The suspicious cylindrical device was discovered around 6:30 a.m. by maintenance personnel arriving for work, said Larry Randa, Valley View School District Spokesman.

At the time, about 10 staff members were in the building along with 20 students who participate in Hermansen PTO's KLH Before-School Club. There are about 689 students, grades K-5, enrolled in the school at 101 Wes Glen Parkway in Romeoville.

Students and staff were moved to the nearby Wesglen Clubhouse as a precaution as police arrived to the school.

School officials decided to cancel classes shortly after 9 a.m. after being informed by authorities that it could be several hours before an "all clear" could be given. Most parents had kept their children home after being notified of the situation via the district's automated telephone system, Randa said.

Complicating the situation was the lack of availability of school buses which were confined to the school district's transportation center because of a nearby oil pipeline leak that occurred yesterday, he said.

By 10 a.m., all 39 students who had come to school had been picked up at the Wesglen Clubhouse by family members.

Once the Cook County Sheriff's Department Bomb Squad determined the device was harmless, Romeoville Police Department officers and school district administrators conducted a thorough search of the school and the surrounding property, and determined that there was no further danger.
