LONDON, Ont. – Police say there were no injuries when a razor blade was found in a trick-or-treater’s candy bag in London.

Police say a double-sided razor blade wrapped in waxed paper was dropped loosely in a child’s bag.

Investigators say they haven’t determined where the razor blade came from as the child visited several homes throughout the evening.

Police are reminding parents to check the candy children have collected when they return from trick-or-treating.
