A young grey seal has been found in Skerries and brought to the Irish Seal Sanctuary suffering from starvation.
The animal was found to have a tag on its flipper that asks the finder to call London Zoo, however London Zoo says it knows nothing about it.
The ISS says the style of tag is not suited to a seal and has caused difficulty to the animal in swimming, which may have resulted in its present starved condition.
The tag was later removed to allow the flipper to heal.
The volunteers at the Irish Seal Sanctuary have sent out a call to all the rehab facilities in the UK and Europe to try to establish where the seal may have originated.
