Four people have been arrested in connection with an under car bomb placed outside a serving police officer's home.
The vehicle was targeted in the Englington Village area outside Derry in June 2015.
Three men and woman aged between 29 and 46 were detained in Belfast, Londonderry and Pomeroy today.
At the time police blamed violent dissident republicans for the attack.
