Durham Regional Police are searching for one male suspect, who they believe may be under 18. They allege he emptied the contents of a poppy donation box at a Subway restaurant on Rossland Road East and left the empty box on the table before leaving.
The suspect is described as a black male, who is between 16 and 20 years of age. He has a medium build and short, black hair. He was wearing a red jacket, black jeans and a white belt.
Police have not released surveillance video images of the suspect because he may be under 18.
Anyone with information about either incident is asked to contact police.
