The Ipswich City Council is scrambling to find a temporary CEO after corruption charges were laid against its most senior employee.
Current CEO Jim Lindsay was arrested in dramatic fashion at the council's headquarters on Thursday, becoming the third senior council figure to face serious allegations of wrongdoing.
Mr Lindsay was charged a day after the council's chief operating officer of works, parks and recreation, Craig Maudsley, was charged with misconduct in relation to public office.
It's alleged Mr Maudsley intentionally abused his authority to benefit a businessman for a council contract over a more deserving business.
Former mayor Paul Pisasale is also accused of extortion, however his case is not believed to be linked to the specific allegations against Mr Lindsay and Mr Maudsley.
The new mayor of Ipswich Andrew Antoniolli, who was elected just a few weeks ago, said Mr Lindsay was on forced leave, and the council is "seeking urgent legal advice to determine its options".
"This comes as a shock, however we must remain resilient through a period of turmoil," he said.
He said the council would soon appoint an external acting CEO, with the council solicitor Daniel Best to act in the role until that person is found.
The mayor said the council would continue to cooperate with the Crime and Corruption Commission, and has promised to address the media on Friday.
