A 16-year-old who helped to prepare a foiled attack on a Taylor Swift concert in Vienna last year has avoided prison.
Mohamed A was given an 18-month suspended sentence under juvenile criminal law in Berlin on Tuesday.
The Syrian, who prosecutors said was radicalised by Islamic State (IS) propaganda on the internet, was 14 when he assisted the would-be attacker by translating bomb-making instructions from Arabic and connecting him with an IS member.
Swift's three sold-out gigs at Vienna's Ernst Happel Stadium were called off last August by concert organisers after the planned attack was uncovered by police.
The court said the teenager made a full confession to the charges.
At the time charges were brought, he was only identified as Mohamed A in line with German privacy laws.
Under a suspended sentence, convicts need to meet certain conditions to avoid being sent to prison.
Three suspects, all of whom were teenagers at the time, have also been detained by Austrian authorities over the plot.
An investigation into the main suspect, identified as Beran A, is ongoing. The 20-year-old Austrian, who is in custody, was arrested before the concerts following a tip-off from the CIA.
The US foreign intelligence service said the plotters had hoped to kill a large number of concert-goers.
In August last year, Swift described the cancellation of her Vienna tour dates as devastating but expressed gratitude to the authorities for preventing a larger tragedy.
