A man has been arrested in connection with an attempted bomb attack on a car owned by the parents of a Northern Ireland police officer.
The 26-year-old was detained in Londonderry.
A device was left under the vehicle in Drumleck Drive, Shantallow, in April.
Homes were evacuated while Army bomb experts dealt with the device.
The serving PSNI officer was not living with his mother and father.
Police blamed dissident republicans for the attack.
Superintendent Chris Yates said the family were targeted in a similar attack in 2009, adding that the device had the potential to cause serious injury.
