A 49-year-old man, arrested in connection with the attempted murder of an off-duty police officer at his home in Londonderry in 2017, has been released unconditionally.
A viable under-car bomb was found at the house in the Ardanlee area on 22 February last year.
It is believed the device, which was designed to detonate once a vehicle drove over a pressure plate, fell from the officer’s car. It later exploded as army bomb experts approached it but no one was injured.
The man was arrested in the Creggan area on Tuesday under the Terrorism Act and later released unconditionally.
