The incident occurred on Tuesday afternoon in the Melbourne CBD, according to Victoria Police. The woman was taken to hospital with multiple stab wounds, treated for serious but non-life-threatening injuries. Her son was not physically harmed.
Police described the attack as random and unprovoked. The alleged attacker, whose identity has not been released, was arrested at the scene and is expected to be charged. The quick intervention of three bystanders, whom police called 'heroic', is credited with preventing further harm.
Chief Commissioner Shane Patton praised the bystanders for their bravery, saying they 'acted without hesitation to protect a vulnerable mother and child'. The incident has reignited debate about public safety in Melbourne, which has seen a series of high-profile random attacks in recent years.
The mother's family issued a statement thanking the bystanders and the medical team, and asking for privacy. The 10-year-old boy is being provided with support services.
The alleged attacker remains in police custody. The exact location of the attack is being withheld pending further investigation. Police are appealing for any witnesses who have not yet come forward.
This case is part of a broader pattern of random assaults in Australian cities, with experts pointing to a mix of mental health issues, drug use, and social dislocation as underlying factors. However, overall violent crime rates in Melbourne remain historically low.
