A man (24) is being questioned by police in Northern Ireland about the murder of a Lithuanian man.
Giedrius Vainauskas (23) was found stabbed at the back of a house in Willow Gardens, Dungannon, last month.
He was taken to hospital where he died a short time later. Mr Vainauskas was a lodger in the house.
An 18-year-old Dungannon man was remanded in custody last week at Omagh Magistrates' Court after being charged with the murder.
