UK coppers are trying to find out how a memory stick containing top secret anti-terror documents was found dumped in the street. The USB memory stick contained 2,000 pages of highly-sensitive and confidential information.

It included how to deal with terrorism on British streets include strategies for acid and petrol bomb attacks, blast control training and the use of batons and shields. Just to be handy there was a list of top terror cop's names, ranks and their divisions.

It was dumped on the pavement outside the police station in Stalybridge, near Manchester where it was found by a  34-year-old businessman who was astounded by the contents when he fitted it into his laptop to check what was on it. Apparently it was not password protected.

He was so shocked he handed it into the press because dropping it into the Cop Shop where he found it might be a bit tricky.
