Two people have been charged in Dublin as part of an investigation into social welfare fraud.

Gardaí and inspectors from the Department of Social Protection estimate that over €1m has been fraudulently claimed over the past few years.

The man in his 30s and a woman in her 20s were released on bail and are due back in court next week. A 19-year-old man is due in court tomorrow to be charged.

A large number of documents including false identification cards have been seized as part of the investigation.

This morning's raids are part of a joint Garda and Department of Social Protection investigation into a family suspected of fraudulently claiming unemployment benefit, child support and other associated welfare payments both here and in the UK.

One individual is believed to have claimed up to €100,000 in his own name with a false identity for eight children, even though he only has two.

Another man is under suspicion for claiming in his and his brother's name.

His brother is in the UK and suspected to be doing the same there.

Detectives from the Garda Bureau of Fraud Investigation and Inspectors from the Department of Social Protection searched the houses in Swords, Clondalkin, Blanchardstown, Balbriggan and Newbridge this morning.

Searches are also being carried out in the UK.

A man in his 20s and a woman in her 40s have been released without charge and a file will be prepared for the DPP.
