Kevin Jonas testifies about McCartney concert in FIFA bribery trial

Pop star Kevin Jonas has served as an unexpected witness in a New York corruption trial involving a top soccer official from South America.

The former Jonas Brothers musician took the witness stand in Brooklyn Federal Court on Thursday (07Dec17) as part of the prosecution's case against defendant Juan Angel Napout, who used to work for soccer's governing body, FIFA.

Napout stands accused of racketeering, wire fraud and money laundering charges.

He has pleaded not guilty to the counts, and throughout the month-long trial, his attorney has repeatedly refused to acknowledge that he accepted bribes, including tickets to a Paul McCartney concert in Buenos Aires, Argentina in November, 2010.

Jonas was called as a witness because he was at the gig.

Kevin told the court he was in the River Plate Stadium crowd with his bandmate brothers Nick and Joe, ahead of their own show at the same venue days later.

His testimony lasted less than three minutes, reports the New York Daily News.
