Gardaí line the streets for Colm Horkan's funeral

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.
