Officers said they pulled over the vehicle Sunday morning because of a broken taillight, but found two Key deer bound with heavy twine in the back seat and a third in the trunk.

The animals are an endangered species.

Officers said the Key deer were bound at the hooves and appeared to be struggling.

U.S. Fish and Wildlife Service officers came for backup and safely untied the animals.

The three deer were released into the wild. Two of them ran off and wellness checks are being conducted on the third.

The men in the vehicle, who were not identified, were arrested on multiple charges, including injuring an endangered species, taking of deer out of season and animal cruelty.
