The protesters, which reportedly included members of the far-right group Golden Dawn, gathered outside an abandoned factory where homeless migrants have taken refuge.
They threw stones at riot police and set fires to garbage bins in Greece's western port of Patras.
A 30-year-old Patras resident was fatally stabbed outside his home on Saturday following a dispute with three men, believed to be Afghan nationals.
A 17-year-old Afghan has been arrested over the case. » | Wednesday, May 23, 2012
