Two bottlenose dolphins dragged a frightened schoolgirl underwater and left her injured after a swimming experience with the animals went wrong. Lexi Yeo, ten, was in the water with the sea creatures at Dolphin Discovery in Cancun, Mexico, when they suddenly turned on her. Her mother Laura-Jane Yeo watched in horror as the youngster was submerged during the TUI holiday. She was eventually rescued from the sea pen when trainers grabbed her on her bodyboard. Lexi suffered cuts, bruises and deep wounds after she was bitten by the dolphins.
