A 44-year-old man being held about the murder of two soldiers at the Massereene Barracks in Co Antrim has been released without charge.
He was detained by the PSNI yesterday following searches in Magherafelt, Co Derry.
23-year-old Mark Quinsey from Birmingham and 21-year-old Patrick Azimkar from London were shot dead as they collected pizzas from delivery men outside the gates of the army base on the 7 March.
They were due to leave for a tour of duty in Afghanistan.
