Dingle Seal and Wildlife Sanctuary has said it is to upgrade its security system and instal infrared cameras in the wake of the discovery of two severed seal heads affixed to its entrance signs.
The incident, which came to light yesterday morning, is under investigation by gardaí and has attracted widespread condemnation and media attention.
Animal rights groups have offered rewards totalling €7,000 for information leading to the arrest and conviction of those responsible.
A statement from the sanctuary today thanked supporters for their "compassionate comments" following the "atrocious scene".
"The pictures are self explanatory in their message, and we are disgusted that a human being could be capable of doing such a thing," said the statement posted on the organisation's Facebook page.
"We are still in shock," the statement added.
"We are in disbelief that we have to do so, but we will be upgrading our security system and installing infrared cameras."
The sanctuary said that despite this "abhorrent" act its volunteers will continue to be there for wildlife in distress and encouraged people to continue to phone if they find an animal in need of help.
