Two people have been arrested in Derry in connection with the Real IRA killing of Kieran Doherty who was shot dead by the dissident group last February.
A 42-year-old man and a 40-year-old woman are believed to have been taken to Antrim custody suite after they were arrested this morning (Tuesday) following a number of house searches in the city.
The woman who has been arrested is believed to be a relative of 31-year-old Mr. Doherty whose body was found dumped in the Braehead Road after he was stripped and tied up by his killers.
The arrests are believed to be the first in connection with the murder which the Real IRA claimed responsibility for accusing the dead man of being involved in drug dealing.
At the time of his death it was claimed that Mr. Doherty was a prominent member of the dissident republican group.
The shooting was widely condemned at the time and Mr. Doherty's family have claimed that MI5 were deeply involved in the killing.
Shortly before he was shot the Derry father of one had approached local media outlets claiming he was being targeted by the intelligence services.
Recently the family had a meeting with Lord Carlile the British government's independent adviser on the activities of the security services.
Lord Carlile travelled to Derry to discuss the case with Mr. Doherty's relatives and said he would speak to the security services before reporting to the Secretary of State.
