According to RTÉ News, the public was warned away from the strand - now reported to be Drumnatinny beach - but a group met at first light this morning where they found four whales still alive in a pool of water and refloated two of them at high tide.
The locals said they watched the whales for several hours to make sure they did not strand themselves again.
But their actions still go against "internationally accepted" practice to leave whales that strand after being refloated to die in peace, as Irish Whale and Dolphin Group (IWDG) welfare officer Paul Kiernan explains.
Meanwhile, a visitor to the area has told the Belfast Telegraph of her horror over scenes on the beach where hundreds of onlookers gathered to see the beached whale pod.
Nicola Hinds from Bangor said some parents encouraged their children to interfere with the carcasses, while others photographed dying whales with camera phones.
She also criticised authorities for not handling the situation better, describing the scene as "an act of total wilful animal cruelty".
IWDG strandings officer Mick O'Connell has since written a column discussing the lessons to be learnt from this incident, calling for the State to establish official procedures for live strandings.
"It is time for State agencies to sit down and decide who has responsibility for live strandings in this country," he writes. "The relevant agency needs to have in place a coastal network of personnel trained in the latest 'best practice' guidelines for dealing with live strandings."
These guidelines, O'Connell adds, must be "backed up with appropriate authority to act as beachmaster when dealing with members of the public, the Gardaí and the Irish Coast Guard service."
