A 38 year old man arrested yesterday in connection with the attempted murder of a police officer in Belfast has been released unconditionally.
It's after the discovery of a bomb under an officer's car at Shandon Park Golf Club last month.
Police are treating the incident in east Belfast on June 1 as the attempted murder of an officer.
Three other people were detained in the city earlier this week.
Speaking after the arrests Detective Inspector Anthony Kelly said: "Since the discovery of an explosive device under the car of a police officer, our investigation has continued at pace.
"By placing this explosive device in a built up area, the terrorists also put the lives of the officer's family, neighbours and members of the public at serious risk.
"It was extremely lucky that no-one was killed or seriously injured.
"We will continue to do everything possible within the law to bring those responsible to justice and information from the public remains important.
