An 18-year-old woman was knocked unconscious in a Salford branch of McDonald's last weekend by a stranger who apparently became enraged when he discovered she was from London.

Megan Westlotorn, a first year sports science student at Salford University, told the Manchester Evening News the man approached her while she was waiting to collect her food order in the early hours of Sunday morning.

“I noticed him talking to people when I went up to get my chicken nuggets," Ms Westlotorn said.

“As soon as he asked where I was from and I said I was from London, he just switched. He started swearing at me and giving me abuse. He called me a f*****g Southerner, saying I was f*****g tramps and that he hated Londoners."

“I stepped back and told him I was backing off from the situation.”
