Two siblings dressed in traditional Jewish clothing, a 25-year-old woman and her 22-year-old brother were stabbed in an unprovoked attack in Melbourne on 19th May.
The attacker is believed to have hit the man over the head before slashing the woman with some sort of blade in cheek.
The man was treated on the scene, but his sister required hospital treatment.
Anti-Defamation Commission Chairman Dr Abramovich condemned the attack, telling a local newspaper that:
“If this assault, which is shocking on many levels, was in fact driven by antisemitism, it should be investigated as a hate crime”.
Wilson Jacob adds that police are investigating whether the incident was racially motivated.
