They say the van approached two young boys near the corner of Anderson and Knox streets and the driver asked if they wanted a ride. They told him no and ran home to tell their parents, who called police.
The driver is described as a white man with gray hair and a gray beard.
At least three other incidents involving a white van approaching children have been reported in McKean County within the last month.
The van pictured is similar to the van police are looking for. It is not the van.
