More than 50 graves have been vandalized at Athens’s largest cemetery in what officials suspect could be the work of a religious sect, police said yesterday. Police said the tombstones of those graves bore the first name Giorgos and were smashed, probably late on Wednesday. «Up until now we have seen damage caused to 50 graves, but the recording of this vandalism is still going on because the cemetery stretches over 70 hectares,» said Maria Koraki, who is in charge of the Third Cemetery, where the vandalism occurred. «It is the first time we have come across such extensive vandalism,» she added. Officials pointed out that individual graves have been damaged in the past as retribution for family grudges, but no large-scale vandalism at the cemetery has ever occurred.
