Police are investigating yet another case of poppy box theft in the Greater Toronto Area.

Oshawa police say a total of $400 was taken from four poppy donation boxes when thieves broke into the White Feather Country store on Raglan Road East late Monday or early Tuesday. It's just the latest in a series of incident since the annual poppy campaign began.

Toronto police are still looking for a man who stole a poppy box from an Etobicoke pizza place Monday night while Hamilton police are searching for a man who was caught on surveillance camera removing two poppy boxes from a pair of Tim Horton's location Thursday.
