Champaign police say people should continue to exercise caution and contact the authorities every time they see a package that looks suspicious.
That word comes after the local bomb squad was called into action once again on Monday on the University of Illinois campus.
Since July, Champaign Deputy Police Chief Troy Daniels said there have been about seven suspicious packages in the city that have been investigated by the bomb squad.
No threat was found in any of those situations, but Daniels said the proper safety precautions have to be taken to ensure the safety of the public and emergency personnel.
He said it isn't clear exactly why there have been so many cases lately, but the public should never hesitate to call 911.
Meanwhile, Daniels said specialized tools and techniques were used to "disrupt" the suitcase on the UI campus on Monday to make sure it was safe to open. He said it was determined that there were no explosives in the suitcase, but it did contain some electronic items, wires and other personal items.
Daniels said investigators believe Monday's incident is isolated and not related to the other packages that have been found.
