Two of the three Irishmen found guilty of training FARC rebels in Colombia have left separate garda stations in Dublin after presenting themselves voluntarily at the stations earlier today.
Martin McCauley left Kilmainham garda station and James Monaghan left Terenure garda station in the company of his solicitor.
Niall Connelly was arrested in connection with passport offences when he presented himself at Harcourt Terrace garda station.
His period of detention has now been extended and he can be held for a further six hours.
Gardaí have said that contact has also been ongoing with the legal representatives of the three men.
RTÉ News revealed earlier this month that the three men had returned to Ireland.
The three had been sentenced to 17 years in prison after an appeal court reversed their earlier acquittal on the charge of training the rebels.
The men have been on the run from the authorities in Colombia since December 2004 when they were released on bail awaiting the appeal decision.
An international arrest warrant was issued for the men who were also found guilty of travelling on false passports.
