Former FIFA vice president Jack Warner has left a jail in Trinidad by ambulance a day after he was charged in a U.S. corruption case that has led to the arrests of more than a dozen international soccer officials and businessman.

Judicial officer Abraham Ali said Thursday that Warner complained of exhaustion and was not able to face questions from reporters gathered outside the jail.

Warner surrendered to authorities Wednesday and was granted a $395,000 bond but spent the night in jail.

He is facing eight counts in the U.S., including conspiracy to defraud and engaging in racketeering. He has not entered a plea and is expected to appear in court in July.

Warner was forced out of FIFA in 2011 over a bribery scandal. He has denied any wrongdoing.
