“No words can adequately express the great sense of loss and revulsion felt by the Donohoe family, the family of An Garda Síochána, and indeed the wider public in learning about the cold blooded murder of Detective Garda Adrian Donohoe last Friday night,” he said.
“We, Adrian’s colleagues, are committed to ensuring that we bring the perpetrators responsible for this callous crime to justice.”
He and 3,000 uniformed and plainclothes gardaí gathered both inside and outside the church and formed a guard of honour as the funeral cortege arrived.
Among the plainclothes officers was Detective Garda Joe Ryan, who was on patrol with Gda Det Donohue when he was killed.

Cardinal Sean Brady concelebrated the Mass with rector of the church Michael Cusack.
Among those in attendance were Taoiseach Enda Kenny, Tánaiste Eamon Gilmore and most of the members of the Cabinet.
Representatives of the opposition parties including Micheál Martin and Timmy Dooley of Fianna Fáil and Gerry Adams and Mary Lou McDonald of Sinn Féin also attended the funeral.
The Defence Forces were represented by the chief of staff Lieutenant General Seán McCann. The Director of Public Prosecutions, Claire Loftus was also in attendance, as were members of the Police Service of Northern Ireland, the North’s justice minister David Ford and secretary of state Theresa Villiers.
