A Florida single-track cyclist crashed and rolled into a swamp. Then an alligator attacked.

An alligator attacked and seriously injured a bicyclist Monday in a Florida park after the rider crashed and rolled down an embankment into a swamp, according to authorities.

The attack happened at Halpatiokee Regional Park in Stuart.

The agency says the victim, identified as Robert Bassett, fell off his bike and then was attacked. WPEC-TV reported that the cyclist was an experienced trail rider.

First responders were on the scene around noon and took the man to a hospital by helicopter. He was reported in serious condition late Monday.

A large alligator was captured in the area a short time later, according to WPTV reporter Jon Shainman. His post included a video of two gators, both of their jaws taped shut.

Halpatiokee Regional Park, at 65 acres, is surrounded by a wetland preserve. “Halpatiokee” is a Seminole Indian word meaning “alligator water.”
