A man is being questioned today about the double murder of a couple set on fire at their home in Northern Ireland.
The suspect, aged 24, was detained in County Armagh where Thomas O'Hare, 33, and his 21-year old girlfriend Lisa McClatchey were beaten with hammers and doused in petrol by self-styled vigilantes.
Both victims died in hospital after fighting for their lives for days following the attack at Foley Road, Tassagh, on November 6.
Six masked intruders are believed to have broken into their home and beaten the pair before setting them alight.
An hour after the attack four men appeared at a hospital across the Irish border in Co Lough with critical burns. They were later transferred for specialist treatment in Dublin where gardaí are monitoring them.
Last night's arrest was the second made by detectives within 24 hours. A 28-year old woman earlier arrested was released last night pending further inquiries, police said.
Another man, David Graham, 43, of Shergrim Glen, Omagh, County Tyrone has already appeared in court charged with perverting the course of justice and withholding information in relation to the murder inquiry.
