Surely the CCTV picked up the one who threw the flare? If so, they should have locked their he gates and let them out one by one until they got him (I presume!)
Shortly after the flare was thrown they was a sizeable number of away fans heading to the exit. Happy to be proved wrong, but I doubt the stewards stopped them whilst they tried to locate the twat who chucked the flare.
