A French banker who is a witness in a major Greek corruption trial was missing Tuesday after violating his house arrest, the justice ministry said.
Jean-Claude Oswald, 58, cut through his ankle monitor after being escorted home by police from court.
A former executive at BNP Paribas, Oswald had been arrested in Abu Dhabi in 2015 to face money laundering charges in Greece.
He is suspected of acting as an intermediary in a number of high-profile state contracts which Greek officials were allegedly bribed to approve.
These include deals with German engineering giant Siemens and several arms contractors: The German company Wegmann, Ericsson of Sweden and Brazilian firm Embraer.
Oswald, who denied knowingly handling bribe money, had been released from pre-trial detention in 2016 after agreeing to cooperate with Greek authorities.
