Bags of cash have been taken away for analysis in the Irish Republic to see if they are linked to a multi-million pound bank raid, north of the border.
Irish police claim six people arrested in the crackdown which uncovered the huge sums of money have connections with the mainstream IRA – Northern Ireland’s largest Catholic paramilitary group.
A seventh, it is alleged, belongs to a dissident faction.
Garda Commissioner Noel Conroy also said one of those arrested is associated with the IRA’s political ally Sinn Fein.
Later, at a court hearing, a man who had been detained in Dublin after police found thousands of euros stuffed into a box of washing powder was charged with membership of an illegal organisation. The 30-year-old, suspected of belonging to the Real IRA, was remanded in custody.
Two others were released without charge.
Over three million euros worth of cash is said to have been seized in police raids this week in the Irish Republic. Investigations are ongoing to establish whether any of the money is from December’s robbery at the Northern Bank in Belfast in which the equivalent of nearly 38 million euros was stolen.
The IRA has always denied any involvement and, speaking in Spain where he is promoting a book, Sinn Fein President Gerry Adams urged people not to rush to judgement in blaming Republicans.
