The blue Peugeot 308 was stolen from Beechfield Road between midnight and 6am on March 5, after the offenders entered a property through a rear door.
Shortly after 6am the same vehicle was in collision with two vehicles in Howards Drive and was abandoned, with three males in dark hoodies being reported running from the scene.
