A dolphin that had become trapped in a lock on the River Medway, Kent, has managed to escape.
The dolphin, which was said to be in good condition when inspected by divers from the British Divers Marine Life Rescue, was spotted in Rochester on Tuesday morning, closer to the sea.
Julia Cable, operations director at the charity, said that animals did pass through the lock “now and then”, but that it was “unusual” for a dolphin.
Generally, common dolphins are found in deeper water and stay out of smaller rivers, she added.
