A prison officer has been before Dublin District Court charged in connection with an investigation into the sale and supply of contraband to prisoners in Mountjoy Prison.
Dillon O'Brien from Clonsilla in Dublin is charged with 14 offences between January 2005 and March 2007.
The 36-year-old is charged with bringing mobile phones, vodka, and heroin into Mountjoy and with having cocaine in his possession on 15 March 2007.
Garda David Carolan gave evidence that Mr O'Brien was arrested at 6.50am this morning.
The court was told that the DPP has directed that he be sent forward for trial at the Circuit Criminal Court. He was remanded on his own bail of €1,000.
He also has to sign on three times a week at Blanchardstown Garda Station.
He will be brought before the court again on 26 August when the Book of Evidence is due to be complete.
Four more men have also been charged in connection with the sale and supply of contraband in the prison.
30-year-old Sean Hinchon and his 28-year-old brother Thomas, both from Clondalkin in Dublin each face three charges of conspiring with prison officer Dillon O'Brien to bring heroin into Mountjoy between 1 January 2005 and 15 March 2007.
They also each face three charges of bringing a mobile phone into the prison on or between the same dates.
27-year-old Paul Dixon from Finglas faces six charges of possessing for sale or supply ecstasy, cannabis resin and cocaine in a cell at Mountjoy Prison.
32-year-old Nigel Curran from Blanchardstown faces two charges of stealing hairdressing products and Ventolin inhalers from a company in City West between 20 February 2007 and 3 April 2007.
All four were released on bail to appear in court again on 29 July.
