Authorities are asking for the public's help as they investigate a report of a man trying to lure kids into his vehicle. 

Lincoln police said three children were walking near Lakeview Elementary School Monday around 4 p.m., when a man in a white van approached them. One child reported the man told the children to get in his van, police said. 

The children ran to the school and alerted authorities. 

Police said investigators are canvassing the area for witnesses and video surveillance, and there is a police presence at the school Tuesday.

Police are asking anyone with information to call 402-441-6000.
