One shopper, a 27-year-old woman, said a seagull snatched a sandwich out of her hands on King Street, The Telegraph reported Monday.

"All I was doing was trying to eat my sandwich and I get attacked by a giant seagull," she said. "It was quite scary -- I had no idea they were so ruthless. It was like that Alfred Hitchcock film, 'The Birds.'"

Catriona Campbell, 19, a sales assistant who works outside on King Street, said the seagulls are "horrible."

"I once saw one land on a man's head. It just reached over and grabbed his pasty out of his hand then flew off," she sad. "It happens all the time. It's because people don't dispose of their leftover food properly and the seagulls take advantage of an easy meal."
