A beachgoer used a piece of broken glass to free two turtles tangled in a discarded net.

The local was going fishing when he noticed the shelled animals stranded in shallow water and restrained by the ghost net in Phuket, Thailand.

Footage shows the resident approaching the first marine animal and using the sharp end of a bottle as a makeshift knife.

He cut the strings wrapped around the reptile's flippers and pushed it back into the sea.

The angler then went to another turtle that had cords wrapped around its neck and carefully cut them.

The second turtle's strings were tied more severely, which caused the glass to break, but the local continued cutting until the animal was freed.

Both animals returned safely into the ocean.

Ghost nets are abandoned, lost, or discarded fishing nets that continue to drift in the ocean long after fishermen leave them behind.

Because they keep moving with currents and do not decompose quickly, they continue to trap, injure, and kill marine animals such as turtles, dolphins, fish, sharks, and seabirds.
