(1966, Kevin Bennett, Sydney Bromley, Derren Nesbitt)

A group of school children act to thwart a robbery.
The bad guy, Skinner (played by Derren Nesbitt) crosses the road near the South End Road fountain in London NW3. In the background are several London Transport AEC Routemasters:

When Skinner gets off the bus, it's followed by a London Transport AEC RT, RT961 (KGU235), which itself is followed to the stop by an AEC Routemaster:
