A teenager's been arrested in connection with the murder of Cameron Reilly.
The body of the 18 year old was discovered in a field in Dunleer, Co. Louth almost three weeks ago. A post mortem showed he was strangled.
Gardai believe he had been on a night out with a group of up to 20 people.
The superintendant heading up the investigation had urged anyone not to fear anyone who had been taking drugs need not be afraid in coming forward with information about Cameron's killing.
An 18 year old man has been picked up this morning and taken to Drogheda Garda Station where he can be questioned for up to 24 hours.
