One of the three Irishmen detained in Colombia last weekend has been charged with falsifying documents and with terrorist activities.
Mr Niall Connolly (36), originally from Glenageary, Co Dublin, appeared before Colombia's general prosecutor yesterday, where he was charged with engaging in "training and military tactics for illegal terrorist activities". If found guilty of the charges he faces a prison sentence of up to 20 years.
The other two men who were arrested in Bogota are Mr Martin McCauley from Lurgan, Co Armagh and Mr James Monaghan from Co Donegal.
Further details are expected to emerge today about the activities of the men.
Garda Commissioner Pat Byrne said last night the men were known to the Garda and were believed to be IRA members.
Security sources said the investigation could take several months to complete. Statements made by the three have been sent to the RUC as part of the initial inquiries but there was no suggestion of any attempted weapons procurement.
