A man has been arrested in Northern Ireland in connection with the murder of two teenagers in Co Armagh five years ago.
Andrew Robb(19) and David McIlwaine (18), both of whom were from Portadown, were stabbed to death on February 18th 2000.
The bodies of the victims were found dumped at the side of a country road near Tandragee, Co Armagh.
Although several arrests have been made in a bid to hunt down the killers, no-one has ever been convicted for the murders.
But police today held a 54-year-old man in a planned operation at his home in Craigavon.
He was being questioned under the Terrorism Act in connection with the investigation into the double murder, a spokesman confirmed.
The frenzied attack on the pair, both from Portadown, came at the height of a loyalist paramilitary feud in the area.
An Ulster Volunteer Force chief was killed outside his home in Portadown a month earlier, and the teenagers were targeted amid fears of a retaliation against the rival Loyalist Volunteer Force.
But police and both victims' families have stressed neither were members of the LVF.
The latest arrest follows a reconstruction on the BBC's Crimewatch programme this week, when a £10,000 reward for information was offered.
It is understood, however, that detectives had been planning the move for some time.
Andrew Robb's mother, Ann, was the victim of a petrol bomb attack on her home in September. She has blamed the UVF for an ongoing harassment campaign.
