In its search for the London bombers, Scotland Yard is now looking for a particular kind of plastic 'family container' manufactured in India and used in the failed July 21 attacks in London.
The London bombers had used Tupperware-like white-lidded containers called a Delta 6250 to build the explosive devices, Metropolitan police deputy assistant commissioner Peter Clarke told reporters.
He asked shopkeepers if they remembered selling 'five or more' of the transparent six and a quarter litre containers, which have white lids.
The brand is marked 'delta 6250 with lid' and says 'family container' and 'superior quality' on a sticker on the container's side.

He said the containers were made in India and sold in about 100 British outlets. "These were manufactured in India, and are exported through one company into this country and then sold in approximately 100 outlets across the United Kingdom," Clarke said.
