STUART, Fla.—An alligator attacked and seriously injured a man at a Florida park Monday, officials said. The attack occurred shortly before noon at Halpatiokee Regional Park in Stuart, according to a Martin County Sheriff’s Office Facebook post. The man was riding a bike when he lost control and fell down an embankment toward a body of water, officials said. The 9-foot alligator grabbed the man, but he was eventually able to break free. Officials said the man crawled away and was assisted by a bystander. Rescue workers secured the area and drove the man more than a mile to meet a medical helicopter, officials said. A professional trapper was called to capture the alligator. State wildlife officers were investigating the attack.
