Note, I Am Not Saying This Never Happened.
But, there are cases of people making up spurious claims of being attacked. I think a woman recently accused a bus driver of racial abuse but her account simply didn't stack up. No CTV evidence even though the alleged incident would have been on camera (at the bus station, I think) if it had happened.
It seems an odd story to me, but perhaps more facts will emerge. And as I said, I am not saying it didn't happen, just that it's all very rum. The wanted man is not wearing a puffa jacket for one thing so doesn't match the description. Perhaps the couple spotted him from old CTV footage, if he is a regular commuter. But, like I said, tis all very odd.
