Ipswich council chief executive officer Jim Lindsay has been charged with official corruption after an investigation by Queensland's Crime and Corruption Commission, the council has confirmed.
The 53-year-old was arrested at the council office this afternoon and taken to the Ipswich watch house where he was charged with official corruption and disobedience to statute law.
Ipswich Mayor Andrew Antoniolli said in a statement Lindsay was on immediate leave and that the Council was seeking urgent legal advice to determine its options.
"This comes as a shock, however we must remain resilient through a period of turmoil," Cr Antoniolli said.
"Council will be seeking to appoint an external acting CEO in the near future.
"Until such time, council city solicitor Daniel Best will act in the CEO role."
A CCC investigation has already seen charges laid against former mayor Paul Pisasale and another senior officer, Craig Maudsley.
Maudsley, the council's chief operating officer (COO) of works, parks and recreation, was charged with misconduct earlier this week for allegedly causing financial detriment to an engineering firm.
The CCC has alleged Maudsley tried to dishonestly gain a benefit for Wayne Frances Innes.
Mr Innes' landfill company, Landfill Logistics, has several contracts with the council.
New plan for council transparency
These latest charges come as Ipswich Mayor Andrew Antoniolli announced a new 19-point plan on Wednesday to ensure transparency and good governance.
The recommendations include a new code of conduct for councillors, open publication of councillors' register of interest, committee reports and all current policies, and tighter policies for procurement and recording potential conflicts of interest.
"Following a similar charge two days ago, I said this council would have zero tolerance when it comes to any illegal activity, and that view remains," he said.
"My office will continue to offer any and all appropriate assistance which may be required by the CCC.
"I again remind people that it is important to allow the legal process to take its course.
"I announced a 19-point plan which will ensure greater transparency when it comes to council business.
"We are answerable to the public, and we must look to operate with the highest standards of integrity that they rightly expect."
Mr Antoniolli is also going to start winding up three of the four controversial council-owned companies.
Mr Lindsay is on the board of directors of all four companies.
The recommendations will be brought before a full council meeting next week.
Lindsay is due to appear in the Brisbane Magistrates Court on October 11.
He has worked for local council for over 30 years, taking over as Ipswich City Council's CEO in May 2014.
