Victoria Police are investigating several aspects of the background of Brendan Nugent, the 43-year-old man charged over an alleged vehicle attack on independent federal MP Helen Haines outside her electorate office in Wangaratta. Police Commissioner Mike Bush confirmed that investigators are examining a reported family rift and the accused man's interactions with neighbours.

The incident occurred on Monday, 19 October 2026, when Haines was allegedly struck by a Toyota Land Cruiser outside her electorate office. The 65-year-old MP suffered catastrophic injuries and remains in critical condition at Melbourne's Alfred Hospital. Her injuries included the loss of both legs.

Nugent has been charged with dangerous driving causing serious injury, intentionally causing serious injury and a federal offence involving harm to a Commonwealth public official. He has been remanded in custody. The charges remain allegations to be determined through the court process.

Commissioner Bush said investigators were keeping multiple possible explanations open while examining the circumstances surrounding the incident. Asked whether police were considering the possibility that the alleged attack was connected to tensions involving Nugent's family, Bush confirmed that this was one line of inquiry.

The commissioner said Nugent's father, Rod Nugent, and his father's partner, Christine Cunningham, had been helpful to investigators. The couple had previously released a statement expressing shock at the incident and confirming their willingness to assist police.

Investigators are also examining interactions between Nugent and people living nearby, including complaints made to police before the alleged attack. Authorities are reviewing how those complaints were handled as part of the broader inquiry. Police have not publicly established a definitive motive.

The investigation has placed additional attention on how police respond when residents report concerning behaviour. Commissioner Bush said the actions of officers in the Wangaratta region would be examined, while also expressing support for local police dealing with the case.

The incident has prompted broader concern about the safety of elected representatives. Politicians across Australia have reported threats and intimidation, and the alleged attack has intensified discussions about security at electorate offices and during public engagements.

Victoria Police have announced a more proactive approach to protecting politicians ahead of the state's election scheduled for 28 November. Commissioner Bush said police would use a central coordination system to assess threats and coordinate responses, while electoral authorities have also discussed security arrangements for voting locations.

The investigation remains ongoing. Police are continuing to gather evidence, examine the accused man's background and assess the circumstances leading up to the alleged attack. Investigators have not announced a final finding about the motive, and the accused remains entitled to the presumption of innocence while the criminal proceedings continue.
