Former Ipswich mayor Paul Pisasale says he will fight charges laid against him after he was granted bail after a night spent behind bars.

The 65-year-old was granted bail on three charges including extortion after he appeared before Brisbane Magistrates Court on Wednesday in a standard-issue brown watchhouse tracksuit. He had been arrested the day before by the Crime and Corruption Commission and charged.

Outside court, Mr Pisasale said he was on his way to the doctor and would be fighting the charges against him.

"All my life people know I have fought for Ipswich and fought for fair and I am going to continue," he said.
