NYPD gives details of July 7 bombs

CNN report that the NYPD claim investigators in London believe the bombers used a peroxide-based explosive called HMDT, or hexamethylene triperoxide, which can be made with such common items as hydrogen peroxide, which is used to bleach hair; citric acid, a food preservative; and heating tablets used by the military for cooking.

NYPD spokesman Paul Browne said the NYPD had clearance from British authorities to present the information during the briefing. Plod AKA Andy trotter Cheif Constable of British Transport Police was upset and said not information should have been released.... sub judice blah blah.

Of course, chats away the man from New Yorks Finest, the sinister details can be found how to make this deadly, and highly volatile explosive on the web.... quite easily e.g

.......included two five-ounce cans labeled citric acid, five tubes labelled hexamine, an empty one-pint bottle labeled Welloxide® liquid stabilizer developer, and a small vial containing a portion of the liquid originally in the Welloxide® bottle. Welloxide® is a hair coloring developer that contains hydrogen peroxide (H2O2) to oxidize hair in the coloring process. The extremely unstable explosive material, hexamethylenetriperoxidediamine (HMTD), can be produced by combining 45 g of 30% hydrogen peroxide, 14 g of hexamine, and 21 g of powdered citric acid (Urbanski 1985)…….. all the required components to prepare HMTD were present, it was necessary to verify the contents of the containers as labelled. This article specifically concerns the analysis of the Welloxide® liquid developer to determine if there was sufficient H2O2 to produce HMTD. Analysis schemes to identify HMTD explosive have been reported (Reutter et al.1983; Zitrin et al. 1983),etc., for 5 pages
