A man suspected of planting an explosive device at National Day festivities has been bailed after giving up his three passports and paying a SFr10,000 ($8,200) bond.
The Federal Criminal Court in Bellinzona overturned an appeal by the Federal Prosecutor's Office for his continued detention.
But magistrates ordered the suspect, in prison since January, to surrender his Irish, Canadian and Japanese papers on release and attend a police station every week.
The 35-year-old is suspected of having planted an explosive device on the historical Rütli meadow in August 2007 at National Day celebrations attended by the then president, Micheline Calmy-Rey. No one was injured.
The Federal Prosecutor's Office argued that the suspect was also behind explosions on September 4 in letterboxes belonging to a parliamentarian, a senator and the president of the Rütli committee.
The man is also suspected of similar attempted attacks last March and July in the canton of Zurich.
