The 21st day of the Aer Lingus Holidays fraud trial at Dublin Circuit Criminal Court was taken up with legal argument in the absence of the jury. The legal argument will continue when the trial resumes on Monday morning and Judge Kieran O'Connor said he would not require the jury before 2 p.m. On trial are Mr Peter Keely, of Carrig Avenue, Dun Laoghaire and Mr Desmond P. Flynn, of Tritonville Avenue, Sandymount, who have pleaded not guilty of conspiracy to defraud. Both men deny they conspired together and with Mr Peter No-one, former financial controller of the company, on dates from March 1987 to November 1988 to defraud Aer Lingus Holidays by misappropriating funds to purchase part of the Los Hibiscos apartment complex in Lanzarote for their own use and benefit.
