The Guardian reported that a former union official told the Big Build royal commission that Mick Gatto, whom the outlet described as an "underworld figure", attended a meeting called after the official and a colleague were seriously assaulted at a construction site. The report was written by Nino Bucci and Jack Larkin. Read The Guardian's report on the royal commission testimony.
According to The Guardian, the witness, Paul Tzimas, a former CFMEU official, told the inquiry that he suffered a fractured ankle in the assault. The outlet also reported that a colleague was left with major injuries and severe PTSD. The summary of the report does not say who carried out the assaults or whether any charges followed.
The Guardian's summary identifies Tzimas as the first witness associated with a matter that the summary does not finish describing, so the nature of that association is not reported here. The summary also does not say when the assault or the meeting took place, where the construction site was, or who else attended the meeting. The material available for this account contains no response from Gatto.
The account rests on a single outlet, and no other report was available for comparison, so the details above reflect only what The Guardian reported Tzimas told the commission. The details are attributed to the outlet and have not been independently verified. Any findings the commission may reach on these matters are not described in the material available.
