One report says they also hit the victim.
President of the Marseilles metropolitan area Eugene Caselli said: “I want to express my profound indignation and rage at this unacceptable act of racist violence.”
French police are allegedly treating the assault as an antisemitic attack rather than simply a robbery.
Though France saw a 45 per cent rise in antisemitic acts during 2012, analyses based on reported crimes suggest that Marseilles is safer than other areas, including Paris.
According to figures from the Jewish security body Service de Protection de la Communauté Juive (SPCJ), 59 attacks were reported in Marseilles between 2009 and 2011, compared to 340 in Paris proper during the same time.
