A GARDA has been arrested for questioning about suspected involvement in the supply of illegal drugs.
The officer - who is based in the south - was arrested on Sunday morning and taken to Mallow Garda Station for questioning.
However, the garda is not based in Cork but attached to a station in another Munster county.
The garda is being questioned by officers attached to the Garda Síochana Ombudsman Commission (GSOC).
It is understood his arrest following a lengthy investigation which was sparked by the receipt of specific intelligence.
The officer can be detained for a period of up to 24 hours.
GSOC officers involved in the operation are working under the Garda Síochana Act, 2005.
Officers must make a decision by Monday on whether to release the Garda or level a charge.
A decision must also be taken on whether to suspend the officer from operational duties.
The investigation into the matter has involved detailed operations in two counties.
