Clissold terrapins attack dogs

According to the Independent (Look out abandoned terrapins about): "Of particular concern is the common snapping turtle, a powerful American species, which has a vicious bite and is known for its aggression. One of the creatures was captured in the trawl of Clissold Park in Stoke Newington, which netted 51 critters, while another was suspected of carrying out attacks on several dogs and a Canada goose in east London."
