Gardaí have made a renewed appeal for information on Derry man Andrew Allen in the lead up to the fourth anniversary of his murder.

Andrew Allen (24) was murdered in his home in 26 Links View Park in Buncrana in Co Donegal in front of his partner on February 9th in 2012.

Gardaí believe that a number of people were involved in planning this murder and subsequently sheltering the killers involved.

To date a number of people have been arrested and questioned in connection with the investigation, including man in his 30s who was arrested in 2015.

Gardaí believe that there are still people in our community who have information which may assist with the investigation.

In a statement, Gardaí say they are appealing for anyone with information or who can assist with this investigation to come forward.
