John Trantham, 25, who works as a carer and has lived next door to the property since February, said: “His mother said he has just found his faith. I have had a number of run ins with him. He kept wanting me to turn my music down or not play music at all, saying he didn’t approve of western hip hop. He has threatened me and I was having to complain to my landlord about it. I thought it was a domestic thing and I’m so shocked it is terror related. It’s really surprised everyone.”
