Rockford Police and a bomb squad closed off the area around Nicor Gas for hours on Friday.
An employee spotted a suspicious package next to the Nicor building, located on Linden Road and called police.
Rockford Police immediately evacuated the building. They also set up a road block in front of the building.
A member of the bomb squad dressed in a protective suit approached the package, but couldn't determine what it was.
Therefore, authorities sent in a remote controlled robot. The robot took a black bag off the package and determined it was a water jug.
