Albion today cautioned supporters against attempting to gain entrance to The Hawthorns with incorrect concessionary tickets.
The Club have conducted a purge on false ticket entrants in the past two games which has seen more than 30 fans stopped from entering the stadium and relieved of their tickets.
The accounts of the offenders have been suspended and three-year bans will be issued.
Mark Miles, Albion’s Operations Director, said the Club would continue to clamp down on anyone endeavouring to “cheat the system” by using concessionary tickets for which they do not qualify.
He said: “This amounts to fraudulent behaviour against the Club and most of all is an insult to thousands of true Baggies fans.
“Of course we recognise these are difficult times which is why we are doing everything we can to ensure we offer the best possible prices to watch football at The Hawthorns. It is deeply regrettable that a small minority still insist on trying to cheat the system.”
Miles also asked travelling fans not to repeat an incident which saw a smoke-grenade thrown on to the pitch at Stoke City during last weekend’s 1-0 victory at the Bet365 Stadium.
It was clearly launched from among the near-3,000 travelling fans and was one of a number of pyrotechnics set off in and around the stadium along with two others confiscated pre-match.
With another 2,000 fans heading for Saturday’s derby against Aston Villa at Villa Park, the Club are anxious there will be no repeat.
“Pyrotechnics are dangerous and will not be tolerated,” he said. “The behaviour of our supporters is the Club’s responsibility and a repeat of this type of behaviour is likely to cause serious difficulties for West Bromwich Albion.
“We have identified the offenders who will be banned for three years and subject to criminal investigation.”
