Algonquin police and Algonquin-Lake in the Hills Fire officials are responding to an unknown object in a wooded area south of Route 62 and north of the creek.

ALGONQUIN - A suspicious object that closed one lane of Route 62 in Algonquin for more than three hours Tuesday turned out to be a painted pipe hidden as part of an outdoor treasure-hunting game, police said.

The PVC pipe painted green that was hidden in a wooded area behind the Algonquin historic village hall was placed there for future participants of the "geocaching" game to find, said Algonquin Deputy Chief Steve Kuzynowski.
