Dissident republicans are believed to be behind the proxy attack attempt on Lurgan police station in March.
A teenage boy, a man and a woman have been arrested by police investigating an attempted car bomb attempt on Lurgan police station.
The dissident republican group the New IRA claimed responsibility for the incident in March that saw a food delivery driver hijacked in Kilwilkie and forced to drive a “crude but viable” device to the station.
Justice Minister Naomi Long said it would have caused devastation if it had detonated.
On Wednesday, police said they had arrested a 48-year-old man and a 15-year-old boy under the Terrorism Act.
Both were taken to Musgrave Serious Crime Suite for questioning.
A police spokesperson added that a 39-year-old woman was subsequently arrested on suspicion of perverting the course of justice, obstructing police and assisting an offender.
All three were arrested in the Lurgan area, where a number of searches remain ongoing.
A Police Service of Northern Ireland spokesperson said: “This cowardly and widely condemned attack, which took place on the night of Monday March 30, put innocent lives at risk.
“I’m keen to offer assurance that we will continue in our efforts to bring those responsible to justice, and would encourage anyone with information to get in touch.”
Anyone with information is asked to contact detectives on 101, quoting reference 1828 of March 30.
