A 39-year-old man has been arrested in connection with a bomb attack on police.
Detectives from the PSNI's serious crime branch detained the suspect in the Belfast area on Thursday morning.
Three officers escaped injury when a bomb partially exploded on the Duncrue towpath near the M5 motorway on March 9.
It is believed to have been detonated by a mobile phone as the officers responded to a call alleging a crime had been committed in the area.
The incident is being treated as attempted murder.
Dissident republicans were blamed for the attack. A gun was later found on the towpath.
