Things have moved on somewhat. DS gave a statement etc. and now has to go do an ID parade. Boy at his school know one of the suspects and has told him he holds a grudge and will come after my DS. Now, this may be hearsay. I looked on the boys facebook page and him and pals are holding their hands in a cross over sort of stance to say they are members of some sort of thing. What would you do? Would I be able to ask the police if he is a member of some sort of gang?
