It's called Ujjal Dosanjh is a Sikh traitor and, at this moment, its still there. The administrator (or perhaps ex-administrator, for under "Admins" it says "There are no admins left in this group!") has asked that no messages advocating violence be posted, and indeed the one demanding that Ujjal be shot ASAP seems to have disappeared. The police know and are monitoring. Get a look before it goes down the memory hole.
PS. I may update this over the course of the day.
