A fisherman on Norris Lake with a very unusual catch.

The Tennessee Wildlife Resource Agency says an alligator was caught yesterday (Monday) afternoon after an angler called authorities after he caught the gator in Dotson Creek, also known as Butcher Hollow.

TWRA says it’s illegal to possess an alligator in Tennessee and releasing them into the wild poses safety and biological threats to humans and the ecosystem.

While the origin of the alligator is unclear, TWRA officials say it is evident that it was being illegally held in captivity and possibly released into Norris Lake.

TWRA took the gator to Little Ponderosa Zoo and Rescue in Anderson County.
