A phial seized on September 5 at the home of one of the suspects held in an anti-terror swoop in Odense contains “a clear liquid consisting of a synthetic mix for the production of triacetone triperoxyde (TATP) and crystals consisting of TATP,” the paper said, quoting a laboratory analysis report.
The lab report was found on Saturday in the street outside the Copenhagen laboratory by a passerby, B.T. said.
Neither the Danish intelligence service PET nor the Odense police would comment on the newspaper report.
Six Danes and a foreigner aged 18 to 33, all Muslims, were arrested in a raid on September 5 suspected of planning terrorist bombings.
In addition to the TATP, police seized chemical fertilizers, bottles of natural gas and pieces of shrapnel, B.T. said.
TATP is relatively easy to make and has surfaced in a number of recent terrorism investigations, including bombings in the Middle East and the London bombings in July 2005.
It was the same type of explosive that Al Qaeda “shoe bomber” Richard Reid tried to detonate on a Miami-bound flight in December 2001, three months after the September 11 attacks in New York and Washington that killed some 3,000.
Although the recipe for TATP is complex, its ingredients can be found in simple household goods: sulfuric acid — found in drain cleaner — hydrogen peroxide, and acetone, often a constituent of nail polish remover.
Once assembled and linked to a detonator, the mix is highly unstable and liable to blow up if exposed to heat or sudden movements.
Bomb-sniffing dogs do not always detect the substance although they can be trained to detect the residual acetone present in TATP.
