A man who threatened to kill a fellow commuter and her father during an unprovoked racial attack on a Melbourne train claimed he was armed with four knives.
Arna Dionysopoulos was on her way home from work on a train travelling from North Melbourne to Footscray about 4.20pm on Wednesday when the man started abusing her after noticing her name on an identification tag. 
The 26-year-old IT consultant was told she should "get out of Australia" and that the man would love to put a gun to her head and pull the trigger, and to do the same to her father.
Ms Dionysopoulos is the daughter of a Greek father and German mother, but was born in Australia.
The Tarneit woman was particularly shaken by the threats towards her father, as he had passed away.
She did not realise the man who was sitting across from her was abusing her at first, as she considers herself Australian.
When the threats escalated, she tried to ignore him and continued reading her book, before getting out of her seat to stand by the door.
Another commuter told the man to calm down, to which he replied that he had four knives and threatened to use them.
Ms Dionysopoulos called police when she got off the train at Footscray, and was grateful for another commuter who accompanied her; especially when they discovered her abuser had followed them.
As she was in arm's reach of the man during the attack, she feared for her safety, and was not confident about catching the train again.
"It's quite shocking that that's what some people believe," she said. "If you live here, you're Australian."
She said that it was possible the man was drug affected, given his erratic behaviour.
Footscray Police First Constable Simone Peirce commended Ms Dionysopoulos for reporting the very disturbing threats, and said everybody had a right to ride a train home from work without fear of being abused.
"Arna is quite upset by it, and it's just unacceptable in today's society."
Ms Dionysopoulos managed to take a photo of the man, who is described as Caucasian, 173cm to 183cm tall with a thin build, and unshaven.
He was wearing a white T-shirt, blue jeans and a dark-coloured cap.
