I took some photos and a video clip of the turnstiles coming out. I emailed the SSC and got a reply to say my email had been forwarded to the security team who "might" get back to me. Haven't heard anything yet.
I also copied FIFA, who responded immediately to say that the European qualifiers were the responsibility of UEFA and that my email would be forwarded to them.
Never seen such a dangerous exit. Had those turnstiles jammed, there could have been serious crush injuries.
