A woman who was groped on a bus has launched a social media campaign to find the man who defended her.
Kaitlyn Regehr posted her story on Facebook, along with a picture of her holding a card saying ‘thank you’ and a thumbs up.
She wrote: “To the man on the 207 bus towards Acton last night (the tall, dark, and dapper one with the beard),
“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.
“Because you were right. I am someone's sister. We all are. And us kids should all stand up for each other.
"The little blond chick in the hat on the 207 towards Acton.
“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!”
In two days the post has been 'liked' close to 50,000 times and shared by more than 25,000 people.
Speaking to Penny Ross and Paul Ross on the BBC Breakfast Show, she said: "He called the guy out loudly enough for the whole bus to hear... It wasn't a show for me, it was this idea of policing the community and deciding what was acceptable for our bus and our community, which was so kind.
"It's so easy for everyone to get in their own bubble and to be honest, he had everything to lose in that situation, so it was so wonderful to see someone step out of their bubble, their comfort zone and intervene."
