HC Deb 22 April 1985 vol 77 c309W
Mr. Chris Smith

asked the Secretary of State for the Home Department on how many occasions during the past 12 months any of the water cannon vehicles based by the Metropolitan police at the river way site in Greenwich have left the site to travel on the public highway; and what was the purpose of their journey on each such occasion.

Mr. Giles Shaw

I understand from the Commissioner of Police of the Metropolis that during the last 12 months the water cannon left the Greenwich site on two occasions for maintenance.
