TORONTO A series of social media posts in Toronto warned that a man or a group of men in a red van were harassing and attacking women. Police are now issuing a warning of their own after a woman who says she was followed for an hour at about 12:30 a.m. Friday morning a short drive away at Bloor and St. Clarens came forward to police. She went for a walk, and she was walking a dog, for about an hour, and throughout the walk the van kept making appearances wherever she went, Constable David Hopkinson told CTV News Toronto.
