A car ploughed into a crowd of pedestrians in Australia's second-largest city on Thursday, injuring at least a dozen people, some of them seriously, officials said.
Victoria state police said they had arrested the driver of a car after it â€œcollided with a number of pedestriansâ€ in downtown Melbourne.
Paramedics were â€œtreating and transporting to hospital 12 peopleâ€, with some seriously injured, Ambulance Victoria added.
Sky News Australia reported that a pre-school child with a head injury was taken to hospital in a serious condition.
A witness, Sue, told Melbourne radio station 3AW that she heard screams before she saw â€œpeople flying everywhereâ€.
â€œWe could hear this noise, as we looked left, we saw this white car, it just mowed everybody down,â€ she said.
â€œPeople are flying everywhere. We heard thump, thump. People are running everywhere.â€
