Gardaí have released a third teenager they were questioning about the murder of two Polish men in Dublin over the weekend.
The 16-year-old was arrested earlier this week, but was released without charge last night.
He was the third teenager questioned over the killings.
Files are being prepared for the DPP in relation to all three suspects.
Twenty-seven-year-old Marius Szwajkos and 26-year-old Pawel Kalita both died in hospital after being stabbed with a screwdriver on the Benbulben Road in Drimnagh on Saturday evening.
