Chicago police are warning fast food delivery drivers on the Southwest side to be more alert.

The warning comes after a series of robberies.

Police say the robbers call in an order for delivery using a cell phone -- and then rob the driver at gunpoint when they arrive.

Three robberies have taken place since October-- with the latest taking place on Sunday.
