Reports published on Thursday by Nine Entertainment mastheads, including WAtoday, The Sydney Morning Herald, The Age and Brisbane Times, said the state's top cop had moved to defend the pursuit after the man suffered critical injuries.
No further details of the chase were included in the reports, including where and when it occurred, who was being pursued, and the circumstances that led officers to begin it.
The public defence of the pursuit indicates the incident has become a matter of concern, and questions are likely to focus on how the chase unfolded and whether it should have been abandoned earlier.
