FREETOWN, Mass. – Officials say a dolphin has been rescued from a Massachusetts river after getting stuck in the mud in a cove.

Freetown animal control officer Linda Podielsky says staff from Inland Fisheries and Wildlife helped the dolphin out of the Assonet River on Saturday. Police helped animal control cradle, lift and pull the animal from Shepard’s Cove and into a trailer.

Inland Fisheries and Wildlife took custody of the dolphin after Saturday’s rescue. It was taken to a laboratory where biologists will assess its condition and determine if it needs any medical treatment.

Police say the dolphin also got stuck in the cove on Friday. It was beached for 8 to 10 hours after getting stuck during low tide. It was eventually able to free itself and swim away.
