Billionaire Chuck Feeney hired a private investigator last July to inquire into allegations that Frank Connolly had travelled to Colombia in 2001 on a false passport.
The investigator, Dermot Benn of Risk Management International, which is based in Dublin, initially gave a qualified bill of health to Mr Connolly when he reported back to Mr Feeney's New York-based charitable foundation, Atlantic Philanthropies.
Mr Benn, a former Army intelligence officer, told Atlantic Philanthropies that gardaí were "not currently concerned" with Mr Connolly.
Mr Benn met John R. Healy, chief executive officer and director of Atlantic Philanthropies, on July 27th, and reported a day later by telephone.
He said that he had been informed by security contacts that the Centre for Public Inquiry (CPI), which had its funding withdrawn last week by Atlantic Philanthropies, was "an august body". He also said gardaí had informed him they had "no concerns on the people" involved in the CPI and there was "nothing on passports".
He is believed to have made a second report to Atlantic Philanthropies some time later, the contents of which could not be confirmed by The Irish Times at the time of writing last night.
Mr Benn is the managing director of RMI Security, while the company's chief executive officer, Cathal O'Neill, is another ex-member of the Defence Forces.
All attempts to contact Mr Benn at his office in Citywest and at his home were unsuccessful yesterday. Mr O'Neill could not be contacted either. The official Irish spokesman for Atlantic Philanthropies, James Morrissey, refused to answer a number of detailed questions, arising from documentation seen by The Irish Times.
It has been confirmed that senior figures in Atlantic Philanthropies met in Dublin in early September for talks on the difficulties caused for the foundation by its association with Mr Connolly, the CPI's executive director. There was concern that the controversy was undermining the reputation of Mr Feeney and the foundation. The meeting outlined a number of options, including asking both Mr Connolly and retired High Court judge Feargus Flood to step down as executive director and chairman, respectively.
Members of Atlantic Philanthropies spoke to Mr Connolly on October 6th and asked him to consider his position "for the well-being" of the CPI.
The executive director of Atlantic Philanthropies, Colin McCrea, could not be contacted last night.
The CPI is to issue a public statement about the Connolly affair in the next couple of days.
