SYDNEY: A Pakistani petrol station attendant was stabbed to death during a horrific crime spree in Australia, authorities said on Friday.

The 29-year-old man was found with multiple stab wounds late on Thursday after allegedly being attacked by two teenage boys.

Police said the pair, aged 15 and 16, went on a rampage, stabbing another man in the stomach, hitting a third with a tyre iron and a fourth with a beer bottle.

Sydney`s Daily Telegraph reported that `IS` appeared to be scrawled in blood on a window at the petrol station, referring to the militant Islamic State group.

Authorities did not confirm the gruesome details but Deputy Commissioner Catherine Burn said `there was physical evidence at the scene which does go to our view that this might be an act of terrorism`.

`We don`t know the motivation. We don`t know what might have led to this. All we know again is that there are very, very serious crimes, she told reporters at a press conference in Sydney.

The two boys were arrested early on Friday after being chased by New South Wales state police into the Australian Capital Territory. -AFP
