An anonymous donor is offering a $10,000 reward for the safe return of a Quebec teen who has been missing for more than a month.

David Fortin disappeared Feb. 10 from Alma, about 250 kilometres north of Quebec City.

Provincial police say they have few leads but believe Fortin, 14, ran away from home.

His parents have said their son might have been the victim of intense bullying.

The 14-year-old was supposed to go to school on the morning he vanished but he never made it.

A Montreal community organization is administering the reward on behalf of the donor.
