Amateur footage has emerged purportedly showing a swimmer frantically trying to reach a shore while being stalked by a large crocodile in Mexico.
Panicked tourists on the overhanging Boca Paila bridge in Sian Ka'an watched in terror, as the man made a beeline for dry land.
A quick-thinking observer intervenes, throwing an object at the creature and stopping it in its tracks. The footage is said to be captured by Manuel Carrera.
