Police say the man who rammed a vehicle into a crowd of pedestrians in Melbourne, Australia, on Thursday had a history of assault, drug use and mental health issues.
The acting commissioner of the Victoria Police told reporters the driver is a 32-year-old Australian citizen of Afghan decent. He was previously known to police for minor offenses.
Both the driver and a 24-year-old man were arrested at the scene.
Authorities say they believe the crash was deliberate but that they don't have any evidence to indicate a connection with terrorism.
The incident sent 19 people to the hospital. A motive is still unknown.
