RCMP say the boy was walking along Hammond Bay Road near Entwhistle Drive Friday around 1:30 p.m. PT when the van pulled up with two white males inside.

Police say the boy ran away and when he arrived at his school told the first adult he saw who called 911.
Nanaimo RCMP responded immediately but were unable to locate the van.
