If the judgement is upheld, it will pave the way for anyone to produce the powerful explosive in Sweden, reports Metro in Gothenburg.
The 18-year-old admitted that he had read about the substance on the internet and made the mixture at home in his kitchen. The stuff is known as TAPT, or triacetone triperoxide, and it is an organic peroxide.
It is more powerful than dynamite and just as delicate as nitroglycerine. But it is not on Sweden’s list of banned substances, which is maintained by the Swedish Rescue Services Agency (SRSA).
“We think that it’s obvious that this substance should require a licence,” said Torkel Schlegel at SRSA to Metro.
He said that a proposal has been submitted regarding the handling of organic peroxides such as TAPT. But the court made its judgement based on the existing list.
Later this year, the Swedish government is expected to introduce legislation that removes the list system. Instead, whole groups of substances will be banned, writes Metro.
TAPT was used in the 2005 London bombings.
