MELBOURNE: A 20-year-old man was arrested over the killing of an Israeli university student who was walking home after a night out with friends in Melbourne, Australia`s second-largest city, police said on Friday.
Homicide detectives took the man into custody as part of an investigation into the killing of Aiia Maasarwe, 21, whose body was found by passers-by near La Trobe University early on Wednesday, Victoria state police said in a statement.
No other details about the man were released.
The arrest came hours before a vigil for Maasarwe, which thousands of people were expected to attend.
Maasarwe was attacked as she returned to the university`s campus in Melbourne`s northeast, where she had been on a study abroad programme, after watching a comedy show. Police described her as an Israeli national.
Australian Prime Minister Scott Morrison offered Maasarwe`s family his heartfelt condolences.
"We must remain vigilant ... I`m so sickened by the attack and frankly disturbed by it, as I`m sure Australians are all around the country," Morrison told reporters in Fiji, where he was winding up a Pacific tour.
He said his centre-right coalition government would announce another "action plan" to stem violence against women ahead of an election expected by May, on top of A$350 million ($252 million) that has already been committed.
Maasarwe`s father is in Melbourne but it was not clear if he would attend the vigil. People have already begun laying flowers at an impromptu shrine that sprang up in parkland near a shopping centre where her body was found.
She grew up in Baqa al-Gharbiyye, a mostly Arab city in the Haifa district of Israel, before moving to China to study at Shanghai University. Her father had a business in China, Australian media reported.
A family member told Australian media this week Maasarwe had been talking on the phone to her sister in Israel as she walked home, a habit she formed so that she felt safer.
She was the second woman killed in similar circumstances in Melbourne in seven months.
Her death has recharged outrage over violence against women after 22-year-old Eurydice Dixon was killed while walking home after performing at a comedy show in June.
The deaths have fuelled a growing sense of frustration, particularly from women who say they are already vigilant and that men have to take responsibility for their own behaviour as well as challenging the views and actions of other men.
"Nothing will change until we change, too. Until we stop blaming `bad men` - while ignoring the sexist attitudes in our society that created them," Victorian Premier Daniel Andrews said.
