First I've heard of this. If true, they'll end up in jail.
A comment appended to the haaretz article:
These hooligans are to Torah what the hilltop boys are to Zionism. That`s not news. What is new is the limp and cowardly response of the police. If any group rioted at the Prime Minister`s Office, can one imagine that no one would be arrested? After the haredim rampaged in Kikar Shabat for the Holy Martyr Vallis and after the haredim rampaged at Haddasah because of an autopsy, the police are afraid to mess with them.
