A SHOCKING Facebook page mocking the fate of four men killed in the Wales' mining disaster is under investigation.
Police received numerous complaints from members of the public who called for action to get the page taken down and a union official condemned the site as "thoroughly sick".
The online attack came as friends and families mourned the deaths of Phillip Hill (45), Charles Breslin (62), David Powell (50) and Garry Jenkins (39) in the Swansea Valley.
The Facebook site took the form of an online hate campaign targeting the Welsh with racial slurs and trivialising the tragic deaths, and appeared to be the work of one person.
One comment read: "In a boost to the failing jobs market in South Wales, 4 new vacancies have been created in the Swansea area from Monday!"
Ian Morgan, an National Union of Miners official based in the Rhondda Valley, said: "I hope they catch the people responsible for this as quickly as possible. It is thoroughly sick.
"Whoever is behind this deserves to be arrested and punished in court with the full force of the law. I hope they are caught quickly and I urge the police to act with rapidity."
A spokesman for the South Wales Police confirmed that a significant number of complaints about the site had been received and it was now under investigation.
Facebook has taken down what it called an offensive page and removed the profiles of its creators.
