Detectives have arrested a man in relation to the suspected theft of €12,000 in cash and other property from a city centre garda station.
Officers from the National Bureau of Criminal Investigation (NBCI) made the arrest following a pre-planned sting operation.
The man, aged in his 40s, was detained in Dublin city centre on Sunday afternoon and was last night being questioned at Crumlin Garda Station.
The suspect was arrested in relation to the theft of the significant cash sum and property from Kevin Street Garda Station.
A garda spokesman confirmed that the male was detained under Section 4 of the Theft and Fraud Offences Act.
It is understood that hidden cameras were used to identify the individual, who until the sting had not been suspected of involvement in the crime.
The €12,000 in cash and property was taken over a period of time, and came to light following an internal audit within the garda station in April.
"A number of members were suspected of involvement in relation to the incident, but have since been proven completely innocent," the source said.
A senior investigator from another garda district was tasked with investigating the incident, and it had recently been determined that cash and property had been stolen from the south inner city garda station.
The stolen cash was seized as a result of a number of operations linked to organised crime in the capital.
The money and property were taken from a store room at the station - where exhibits and seized cash are kept - and is meant to be a secure area.
Kevin Street Garda Station, located in Dublin 8, polices an area where some of the senior members involved in the ongoing Hutch/Kinahan feud reside.
Officers attached to the station have had several successes against organised crime in recent years under Operation Thistle, which targets low and mid-level dealers linked to the gangs.
There have been a number of occasions in recent years in which sums of cash have gone missing from Dublin garda stations. In June 2013, it emerged that €27,000 - which was being kept in a safe at Malahide Garda Station - was missing.
It had been recovered by off-icers following a robbery at the Coolock branch of Woodie's DIY chain on Malahide Road, which took place in June 2009.
