GARDA and the PSNI are set to investigate a comment made last week by a Sinn Fein official in relation to the murder of Paul Quinn.
The official is believed to have suggested the same people who killed Paul Quinn in 2007 where responsible for the murder of Detective Garda Adrian Donohoe earlier in the year.
A Sinn Fein press officer, Mark McLernon, linked a well known Republican family to the two murders.
Sinn Fein have since said that he was merely referring to hearsay relating to the murders of both men.
In a statement on the matter sent to the Monaghan Democrat, Sinn Fein said: “He gave an off-the-record briefing to a Sunday World journalist in which he referred to local rumours and speculation around these killings, all of which is already in the public domain. This includes a recent investigation into these matters by the Sunday World itself.”
Pressure is also mounting on Deputy Gerry Adams to make a statement on the matter, which he so far refused to do.
When asked for a statement on the matter the Monaghan Democrat was referred to the appearance of Sinn Fein MP Conor Murphy on LMFM, in which he said: “Sinn Féin elected representatives, including Louth TD and Party Leader Gerry Adams have met senior Gardai in Dundalk and discussed the Garda investigation into the killing of Garda Adrian Donohoe.
“Sinn Fein made very clear to the Garda representatives our full support for their efforts into this murder.”
The press officer has now said he fears for his personal safety. Gardaí are now set to liase with PSNI on the matter.
