The Garda emergency response unit was called to a closed Cork City Garda station last night after a man in his 60s threatened to set himself alight.

A spokesperson for the Army Bomb Disposal unit has said a viable pipe bomb brought into a Cork city garda station this morning could have seriously injured or killed someone had it detonated.

A man was being questioned at a Cork City Garda station last night following what is believed to be the largest heroin seizure in the city this year.
