IPSWICH City Council engaged an investigator to substantiate claims of misconduct by a female officer in the so-called "Tomatogate" scandal, it has been revealed.
The investigation "proved to be inconclusive", but council chief executive Carl Wulff said the employee in question had left her position before Christmas through mutual agreement.
The investigator was attached to council's internal audit team.
The allegations arose from an incident at the Tomato Brothers restaurant in Limestone St, in which the council officer was alleged to have threatened to have the eatery shut down after a row about customer service.
Mr Wulff said the employee concerned did not want to renew her contract and the separation between the two parties was by mutual agreement.
"At no time was the employee dismissed by council," he said.
"Council was concerned about the allegation that the employee had made an intimation regarding the use of her position at council, which could be deemed a breach of the Code of Conduct.
"Council's investigation into this matter proved to be inconclusive as there was not enough verifiable evidence that the employee had breached the code."
Mr Wulff said because most of the alleged issues occurred in the employee's own time the council had no jurisdiction.
Mayor Paul Pisasale said the council officer was offered a new contract but had not accepted it.
"She was offered a new contract at the end of the year, but she didn't take it up," he said.
