One of the London Bridge attackers, Khuram Butt, used to visit the Ummah gym in Barking.

Reporter Manveen Rana first spoke to the receptionist who, having previously denied meeting Butt, said "he was quite a kind person...he didn't look like one of those extremists".

One regular gym goer also said: "In the gym there's a lot of big, scary guys and then there's him just there in the corner, humble, quiet, small."
