Area law enforcement officials are searching for an older style, white van driven by a white male in his late 60s or early 70s. The individual in the van reportedly attempted to make contact with two young students at a Spencer elementary school playground earlier today. Similar incidents have occurred throughout northwest Iowa in the last two weeks. Individuals with information should contact their nearest law enforcement agency. Spencer Police Chief Mark Lawson is reminding parents to educate their children not to talk to strangers or get into a stranger's vehicle.
