Expatica reports a three-judge panel also found that the defendant, identified as Bilal L., also tried to convince men that he met during a 10-month jail sentence for threatening a member of parliament to supply explosives and other weapons.
The 21-year-old, who worked as a pizza deliveryman in Amsterdam, has been twice named as a suspect in more serious cases that have come to nothing. An informant said he was involved in the killing of filmmaker Theo Van Gogh but recanted, saying he had been pressured into his earlier statement.
In another case, a newspaper said Bilal had been scouting out potential places for terrorist attacks in Amsterdam's red light district while making deliveries.
