Police have launched an urgent appeal after CCTV shows a man allegedly smearing faeces on two synagogues and along a passageway used by worshippers in north London. The anti-Semitic attacks took place last Wednesday, Thursday and Sunday in Golders Green, and are being investigated by Metropolitan Police as criminal damage. Det Supt Tony Bellis said: "This is a revolting and appalling act and we are urging the public to help us locate those responsible as soon as possible." Volunteers from Shomrim North West London, which patrol areas including Golders Green, Hendon and Finchley, gathered the CCTV footage and passed it on to police.
