GARDAI are investigating links between a Dublin-based suspected fraudster and the financing of Islamic State.
The man, who is originally from Libya but is living in Clonee in Dublin, is at the centre of a €100,000 fraud probe.
While Gardaí were investigating the fraud allegations they discovered potential links between him and the funding of the Islamic State group.
There are now concerns that the man is involved in financial crimes here to help fund the terror organisation.
The investigation is Gardaí investigate suspected financier at centre of €100k fraud probe at an early stage, but if convicted the man is likely to be jailed before being deported.
Gardaí have stepped up efforts to crack down on terror networks in the wake of recent attacks in the U.K. and other European countries.
There have been a number of arrests of individuals here in recent weeks as part of probes into links between individuals based in Ireland and Middle Eastern terror groups.
London Bridge terrorist Rachid Redouane married his wife in Dublin in 2012 and lived here for some time.
Gardaí arrested two men in Wexford and Limerick with suspected links to Redouane in the aftermath of the London attacks.
Both men had been using documentation in the name of Redouane, including a PPS number, but were not suspected of any involvement in the attack.
However, Gardaí have made arrests of a number of people suspected of links to terror groups here.
Last month, Gardaí swooped on an apartment in south Dublin and arrested a Moroccan man suspected of involvement in money laundering.
