NORWALK - A number of southwestern Connecticut communities are investigating apparent incidents of stranger danger involving a blue and a white van.

Norwalk police are investigating after a suspicious blue van and a white van were spotted at a school bus stop at the Meadow Gardens Housing Complex. 

Redding police are also investigating after a white van slowed down near a school bus on Tuesday. Similar reports were also made in Bethel and Danbury.

Police tell News 12 Connecticut that they don't know if the incidents are connected or if the same person was involved. 

In each case, the vans drove by areas where there were children. 

Both Norwalk and Redding school districts are providing extra patrols at bus stops.
