River Dee dolphin is being returned to open waters

A dolphin which has been swimming in the River Dee near Chester is being returned to open waters.

It's thought the animal was hunting for food when it found its way 30-miles inland and was unable adjust to the unfamiliar tidal flow.

The RNLI said it became stranded this morning and has been taken by boat to the Irish Sea where it will be released back into familiar territory.
