Man released unconditionally in pipe bomb investigation
A man who was arrested by police investigating a pipe-bomb attack on a car belonging to the parents of a serving PSNI officer has been released.
The device, which was found under the couple's car at Drumleck Drive in Shantallow, Londonderry on 15 April was made safe by army bomb experts.
The 26-year-old man, who was detained in the city on Monday, has been released unconditionally.
The PSNI officer does not live in the house.
Police blamed dissident republicans for the attack which they are treating as attempted murder.
