LONDON - A Canadian woman who says she was grabbed by a man on a city bus in London wants to thank another man who intervened and confronted her attacker.

Kaitlyn Regehr posted on her Facebook page this week that the incident occurred on Tuesday.

Her post says the man who came to her rescue told the person who grabbed her buttocks that it was not acceptable.

Regehr, who is from Toronto, is asking for help to "find this awesome dude" so she can "buy him a pint."

Her Facebook post, which has 85,000 likes, is accompanied by a photo of her holding up a sign that says "thank you."

The story has also been picked up by a number of media outlets in Britain including the Daily Telegraph and the BBC.
