Via Jerusalem Post :
A group of approximately 20 youths attacked a local Synagogue in the English suburb of Stamford Hill, yelling threats and vandalizing property, a Hebrew language new-site reported on Sunday.
One witness belonging to the “Ahavat Torah” congregation described the mob as shouting “we will kill you” as they proceeded to physically assault the worshipers inside the synagogue and tear apart prayer books.
Another Jewish local who had passed by the scene rushed inside, grabbing one of the suspects with the intention of bringing him to the police, but was quickly overwhelmed by the other attackers and suffered strikes to the face, losing a tooth.
A spokesmen for local law enforcement said that the police views the assault on the heavily Jewish populated Stamford Hill community gravely and that they have already detained four suspects who say they were involved in the incident.
