P.C. Ken Melvin and P.C. Reg Hollis stop a young man for erratic driving, and a PNC check reveals the expensive car is stolen. Stamp and Quinnan arrive to transport the prisoner to Barton Street, and Melvin and Hollis volunteer to drive the car back to Sun Hill. As Melvin moves some of the building materials from the station renovations so he can park, the car explodes in a huge fireball. Hollis, Conway and Melvin are rushed to hospital - but Ken Melvin soon dies from his injuries. SO13 arrive at Barton Street to interview the car thief, who it turns out stole the car from an army major who was a likely terrorist target. Sgt. Cryer is outraged that the disaster could have been prevented as SO13 had the major under surveillance and could have stopped the car being stolen. (thetvdb.com)
