A Norwegian citizen of Somali background has been arrested in Britain and is now in a jail outside London. He is charged with allegedly having supplied radioactive materials to be used for terrorism. The 52-year-old man who became a Norwegian citizen in 1997, was arrested in London in September, after he according to the charges had supplied a kilo of the radioactive material red mercury, the newspaper VG writes. Red mercury is supposedly an ingridient in so-called "dirty bombs".The jailed Somali/Norwegian has together with two other men been charged with conspiring to buy the red mercury with the aim to use it in a terrorist action, the newspaper writes. The three pleaded not guilty when they were brought before the Old Bailey court last Monday. According to VG the Norwegian Security police has been informed. The Norwegian Foreign Office has been informed, but does not want to comment. However, they say they are ready to offer consular assistance to the arrested man.
