In February last year an appeals court upheld the conviction of the alleged pilot and four others with sentences of up to eight years in prison for their involvement in the spectacular robbery.
A stolen helicopter had been flown to the roof of the money depot. The armed robbers then broke in through the glass roof and stole the equivalent of millions of dollars.
New information indicates that the helicopter landed 45 minutes later than originally believed, which the defence says was just after the alleged pilot was filmed by a surveillance camera at a fast food restaurant. In light of the new evidence the public prosecutor has decided to reopen the investigation.
