Two men arrested by police investigating the murder attempt on PSNI officer Constable Peadar Heffron earlier this month have been released without charge.
The 33-year-old police officer was very seriously injured in the bomb attack earlier this month.
A 33-year-old man held following a raid in north Belfast on Monday was released unconditionally last night.
A 34-year-old man arrested in west Belfast by detectives from the serious crimes branch of the PSNI was released earlier.
Constable Heffron remains in a critical but stable condition in Belfast’s Royal Victoria Hospital. He had a leg amputated after he was seriously injured when a device exploded under his car as he left his Randalstown home for duty at Woodbourne station in west Belfast on January 8th.
The Irish language specialist and Gaelic footballer was targeted by dissident republicans because he was a Catholic and a high-profile officer in language and sporting circles, the PSNI believes.
