Two men, aged 30 and 33, and a 17-year-old boy remain in custody after being arrested on suspicion of the murder of a man shot dead in north Belfast over the weekend.
A 27-year-old man also arrested in connection with the killing at Etna Drive on Saturday afternoon has since been released unconditionally.
The victim – 36-year-old Robbie Lawlor, from Coolock in Dublin – was shot multiple times by a lone gunman in what police have described as a “brutal killing”.
Detectives are appealing for help with their investigation.
They are asking anyone with CCTV, dash-cam or mobile phone footage recorded in the Etna Drive or Kingston Court areas on Saturday to upload it to the Major Incident Public Portal.
