According to La Tercera, his friend Alejandro Becerra, aged 18, was driving Vidal's Dodge Caliber 2011 when the police stopped him for some reason.
The guy tried to bribe the authorities with $50,000 and a Juventus jersey with Vidal's number and name on it. He was taken in for bribery.
The police won't release the car unless the owner himself comes to get it, so Vidal might have to fly to Chile after the Cesena game.
