Funeral of murdered garda detective sees fellow gardai line the streets of Charlestown, County Mayo.
Two of the detective garda’s brothers were among those to pay tribute during the service in his hometown of Charlestown, Co Mayo.
Garda Commissioner Drew Harris addressed mourners, saying his colleague’s courage was on show the night he died when he stepped forward to be counted at the crucial moment.
Mr Horkan, 49, was shot dead on Wednesday in the town of Castlerea in Co Roscommon when he intervened in an incident unfolding close to the town’s Garda station.
A man had been charged with murder.
On Sunday, gardai lined the streets of Charlestown as the coffin carrying Mr Horkan’s body was carried to St James’s Church – the same church where he had been baptised.
