West Brom are working with police after footage emerged of supporters appearing to let off fire extinguishers . West Brom supporters threw seats into sections of the Villa fans during the second half with Pulis insisting the day after the match that anyone found guilty should be banned for life. Pulis remained detached from all disciplinary issues on Thursday, ranging from Brunts case to the crowd trouble and whether his winger Callum McManaman was struck in the tunnel after the game. Thats ongoing and its something Im not involved in, he said about the disturbing scenes. Thats down to the powers-that-be who are above me. Its up to them to sort that out and well see where that takes us. But at the moment I dont think theres any comment from ourselves or the FA. Police and the FA are investigating the behaviour of both clubs after the unruly scenes in which some West Brom players are also alleged to have tried to trip Villa fans . Tony Pulis has called for supporters to behave themselves, or be punished properly . Pulis did, however, reiterate the need for common sense from supporters. You want derbies to be passionate and committed but there are certain levels, certain rules, that we should all stay and work within, he said. If people have broken those rules then they should be punished and punished properly, because you cant have a situation like weve had 20 or 30 years back where its just chaos. Weve moved on as a country from that and we have to make sure we dont allow it to come back in. As for possible lifetime bans for supporters, Pulis said: Thats down to the club.
