Gardaí have issued a further appeal for information over the murder of Detective Garda Adrian Donohoe in Louth and in particular a white truck.

The truck was parked on Shean Road, Forkhill near Newry at around 9.45pm on the night of his murder, 25 January.

Gardaí say the truck may have been broken down and a number of people were seen around the vehicle.

They want to establish the identity of the driver or owner of the vehicle or the identity of any person who was around it on the night.

Detectives are also looking to identify any person who may have been involved in the recovery of the vehicle or any person who may have been involved in the service of the vehicle on that day.

They are also looking to locate the drivers of any other vehicles that may have been travelling on the Shean Road on 25 January at around 9.45pm.

Gardaí are appealing for any of the above to come forward and contact them in Dundalk on 042 9388400.
