An Ipswich solicitor has been charged with extortion over his reported involvement in an incident connected to former mayor Paul Pisasale.
Cameron McKenzie was released on watch house bail on Thursday, avoiding an appearance in Brisbane Magistrates Court.
The 35-year-old was arrested hours earlier after an investigation by Queensland's Crime and Corruption Commission.
It came exactly one month after Pisasale was charged with extortion and assault offences.
McKenzie established LPM Lawyers with a colleague earlier this year and was a junior vice-president at the Ipswich Chamber of Commerce and Industry.
President Phillip Bell learned of his board member's arrest through the media.
Mr Bell told AAP the chamber had not received any additional information.
"As a chamber we were surprised to see Mr McKenzie arrested and charged," he said on Thursday.
"We can only presume it relates to a personal matter."
Mr Bell said he was yet to speak to McKenzie about the allegations.
"I'm not surprised that the chamber is not his first point of contact after today's events," he said.
Mr Bell said once McKenzie made contact, the board would "take advice" on what to do about his position.
McKenzie's matter will be brought before the court on August 4.
