GARDAI say they believe a number of people are sheltering those involved in the murder of a Derry man in Inishowen six years ago.
Andrew Allen was killed in front of his partner at his home in Links View Park, Buncrana on February 9, 2012.
The 24 year old was shot a number of times and was pronounced dead at the scene.
Dissident republican vigilante group RAAD carried out the murder.
It claimed the 24-year-old was a drug dealer, a claim rejected by his family.
Last September, an inquest into Mr Allen’s murder was adjourned at the request of Gardai.
A senior officer told the Coroner that the murder probe was “still a live investigation”
Gardai believe the killers had travelled from Derry to shoot Mr Allen dead.
On the six anniversary of his brutal killing, Gardai have renewed their appeal for information in relation to his murder, and believe that a number of people were involved in the “destruction of evidence.”
A silver Vauxhall Cavalier believed to be involved in the murder was found on fire in Fahan shortly after the shooting.
There has been a number of arrests in connection with the investigation but nobody has ever been charged.
Gardai particularly want to speak to anyone who may have seen suspicious activity around the scene of the shooting or where the burning car was located.
A spokesman said: “An Garda Siochana are grateful for all the witnesses that have come forward and made statements but gardai believe that there are still people in both Buncrana and Derry city who have information that may assist with the investigation.”
Anyone with information is asked to contact Buncrana Garda Station on 074 93 20540, the Garda Confidential Telephone Line on 1800 666 111 or any garda station.
