The family of a man murdered over 40 years ago in Co Louth has described their first meeting with a Garda Commissioner as positive.

Forestry worker Seamus Ludlow's body was found in a ditch with bullet wounds near his home on the Cooley peninsula, Co Louth on 1 May 1976.

The family of the 47-year-old want a new investigation opened into his murder.

This morning they met Commissioner Drew Harris in Garda Headquarters in Dublin.

Mr Ludlow's nephews said they will fight for justice for their uncle "as long as there's breath in our bodies".

The family has long maintained he was an innocent victim of a loyalist death squad comprising a Red Hand Commando and two members of the Ulster Defence Regiment.

They also believe gardaí were complicit in spreading false rumours that Mr Ludlow was killed for being an IRA informant and that some family members had prior knowledge it was planned.

The State previously apologised to the family over the failures of the garda investigation into what it described as the "callous sectarian murder" of Mr Ludlow in 1976.

Mr Ludlow's relatives previously lost a High Court action to force the Minister for Justice to open inquiries into the State's handling of investigations into his death.
