HC Deb 23 November 1981 vol 13 c284W
Mr. Michael Brown

asked the Secretary of State for the Home Department how many incendiary devices, which could have caused an explosion, have been found in London during the last two months.

Mr. Mayhew

Of the six explosive devices dealt with by explosives officers of the Metropolitan Police during the last two months, none was an incendiary device. Finds of other incendiary devices by the police are not recorded centrally and the information could not be obtained without disproportionate cost.
