Police in Northern Ireland arrested a 25-year-old man at Hillsborough in Co Down this morning and are questioning him in connection with the murders of two teenagers in Co Armagh five years ago.
Andrew Robb, aged 19, and 18-year-old David McIlwaine, both from Portadown, were stabbed to death in February 2000.
Their bodies were found on the Druminure Road outside Tandragee, a few hours after they had left a disco.
Another 25-year-old man arrested yesterday in Coalisland, Co Tyrone, is still being questioned.
A 54-year-old man arrested by the PSNI on Saturday in connection with the double killing has been released.
A report will be sent to the Public Prosecution Service.
The frenzied attack on the teenagers, 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.
However, police and both victims' families have stressed neither were LVF members.
The arrests followed a reconstruction on the BBC's Crimewatch programme last week, when a £10,000 reward for information was offered.
