Two men have been arrested in relation to a murder which police had originally believed to be a missing person case.
The men, aged 39 and 58, were remanded in police detention last night by detectives investigating the murder of Leslie White.
Mr White (69), from Armagh, disappeared last year after travelling across the border to Monaghan.
It was originally believed he had gone missing and a search operation was launched.
But detectives now believe he was abducted and murdered in the Republic of Ireland.
Mr White was last seen in the Lurgan area on Saturday November 6, 2010.
In January this year police made a nationwide appeal on the BBC’s Crimewatch programme for any information which could help to pinpoint his last movements.
At the time of his disappearance he was due to face trial in relation to a drugs haul worth more than £200,000 in Co Offaly.
It has been claimed he was linked to a drugs trafficking operation with a notorious Northern Ireland-based gang, and sources have claimed he was murdered in the Republic and his body dumped.
Mr White had previously been linked to a number of criminal investigations.
During an earlier spell in prison, Mr White was severely scalded with boiling water after being attacked by dissident republicans.
The two arrested men were taken to Musgrave Street police station in Belfast.
