From the Taxi trade Paper

Usually not too much attention is paid to a
parked taxi especially when it is by a taxi
shelter; after all, cabs are left there regularly
by drivers stopping for something to eat. But

police and resulted in a great deal of disruption
to the area.
The cab had been parked for a number
of hours and fellow cab drivers believing that
it might have been stolen and dumped contacted
the police. In the back of the cab
there was a large blue plastic container and
a load of newspapers.
It was the blue container that caused
the police to be twitchy and they cordoned
off the area amid fears that the cab could be
packed with explosives, in another failed
bomb attack on London.
Police explosive experts called in a remote-
controlled robot to remove the windows
of the cab so the blue container could
be examined. It was eventually declared
safe, the cordon lifted and traffic gradually
returned to normal.
The blue plastic container was the kind
