Woman assaulted on a bus launches viral Facebook hunt for the Good Samaritan who stood in to protect her

Kaitlyn Regehr, a Toronto-born broadcaster, filmmaker and burlesque expert based in London, shared a photo of herself (left) holding a sign that reads 'thank you!' to her Facebook page, along with a lengthy tribute (right) to the mystery 'tall, dark, and dapper' stranger. She claims she was 'grabbed' by a man on a bus last week while on the 207 evening bus service to Acton, London.

The post, which has been 'liked' by more than 45,000 people, reads: 'To the man on the 207 bus towards Acton last night... Thank you for saying something when that man grabbed me. Thank you for insisting that it was not acceptable.' 'Most of all, thank you for asking him about the women in his life, his mother, his sister... You said, "She could be your sister. She is someone's sister", and in doing so you made me a person. You made us a community.

'I thank you not just because you stood up for me, or because you made me feel safe, but because on your transit home - in this big, potentially anonymous city - you humanised assault. You didn't turn away. You took a stand. You said something.' 'Please, let's all endeavour to "say something", please share, and please help me find this awesome dude so I can buy him a pint!'
