TORONTO - Toronto police are looking for a man they say is snapping photos of women's underwear up their skirts on the subway.

It's believed the photos are shot using a cellphone.

Police say the victims include teenage girls.

Investigators are looking into two incidents but say some victims may not realize a photo was taken.

They're warning women to be careful when travelling by subway.

The suspect is described as white, tall, about 40 years old, with thin-rimmed glasses.
