A prison officer accused of smuggling cannabis and cocaine into Mountjoy jail is expected to face further charges, a court has been told.
Jarlath Walsh, from north Dublin, was stopped during a routine search going in to work at the jail on Monday morning and was arrested.
The 39-year-old appeared before Dublin District Court on two charges of possession of drugs and two charges of possession with intent to supply.
Judge Aingeal Ni Chonduin granted the prison officer bail for eight weeks.
Detective Garda Fergal O'Flaherty told the court: "It is envisaged there will be further charges."
The judge told Walsh not to contact any prison staff at Mountjoy before his next court appearance on February 15. He was also told to sign on at a local Garda station and surrender his passport.
Other bail conditions included a 1,000-euro bond from Walsh and an independent surety of 5,000, agreed by Walsh's father James.
The prison officer's solicitor, Yvonne Bambury, warned his father: "You will lose your money if he fails to appear."
Authorities said they found 450g (1lb) of cannabis and quantities of cocaine, prescription drugs, heroin and skunk, a more potent form of cannabis, on Walsh when they arrested him.
So far, Walsh is only charged with possession of, and possession with intent to supply, cocaine and cannabis.
