A tragic video shows a huge crocodile zoom towards a man swimming in a Mexican lagoon before dragging him underwater to die.
The unnamed man, reported to be in his 50s or 60s, apparently ignored signs warning it was prohibited to swim in the water because it was heaving with crocodiles.
His leg was bitten off and he died the same day, on October 17.
The incident, at Laguna del Carpintero in the Mexican state of Tamaulipas, was witnessed by a camerawoman on the shore who filmed the scenes with her mobile phone.
Footage shows the moment at least one huge crocodile can be seen rapidly gaining on the man as he swims towards the shore.
He is quickly caught by the three-metre animal and dragged underwater, followed by a whip-like thrash of the crocodile’s tail as it dives down.
The woman recording shouts in horror as the water is left eerily quiet as both the swimmer and croc vanish from sight.
Crocodiles kill their prey by dragging it underwater to drown and then stash the carcass.
Emergency services were contacted and rescuers tried to find the tragic man by searching in boats.
The body was located at the bottom of the lagoon and recovered before any more of it could be eaten.
When they recovered the body, emergency services said the man had severe injuries to his neck, arms, and chest and his leg was bitten off.
The man has not been identified but is believed to have been a homeless man living in the region.
Local authorities ban swimming and water sports in the lagoon due to the presence of crocodiles.
