MELBOURNE: A car ploughed into a crowd in Australia’s second-largest city on yesterday injuring 19 people in what police said was a “deliberate act” but one they did not believe was terror related, reports AFP.

Witnesses said people were thrown through the air after being hit by the vehicle, which did not appear to be trying to stop as it “mowed everybody down” at a busy intersection in downtown Melbourne.

Victoria state police said the 32-year-old driver, an Australian of Afghan descent, was known to authorities for traffic and “minor assault” offences and had mental health issues.

The car was driven “intentionally” through the intersection and collided with a “large number” of pedestrians, Acting Chief Commissioner Shane Patton told reporters in Melbourne.

The driver “has a history of drug use and mental health issues... At this time we do not have any evidence or intelligence to indicate a connection with terrorism” or extremism, he said.

The man was arrested after a tussle with an off-duty police officer.

Investigators were waiting to interview the driver, who was in hospital under police guard.

Victoria state Premier Daniel Andrews, called the incident an “evil, deliberate, cowardly act” that left 19 people hurt—four of them critically.

In a tweet, police appealed to members of the public to upload any images they might have of the incident to help assist with their investigation.

A witness, named only as Sue, told Melbourne radio station 3AW that she heard screams and saw “people flying everywhere”.
