CHELSEA fans have been warned bad behaviour will be acted upon at the Amex.

Albion have reminded spectators of their zero tolerance policy ahead of Sunday’s Premier League fixture.

It follows an outcry after footage showed a Chelsea supporter allegedly racially abusing Raheem Sterling during their weekend win over Manchester City at Stamford Bridge.

Albion chief executive Paul Barber told The Argus: “We’ve got clear policies and guidelines with regard to spectator conduct in the stadium.

“We’ve got well-trained stewards who are well aware of what is and isn’t acceptable.

“We’ve got very sophisticated technology, which is amongst the best in Europe, if not the world, for giving us the evidence we need to take action against anyone that transgresses that expected conduct.

“Likewise, some of our stewards will be wearing – and are always wearing – body cams, so they will pick up things people don’t even realise they are picking up.”

Meanwhile, Chelsea have suspended four people from attending their matches, pending further investigations into allegations regarding the behaviour of supporters towards Sterling during Saturday’s match with Manchester City.

A statement published on the club’s website read: “Chelsea Football Club has suspended four people from attending Chelsea matches pending further investigations into allegations regarding the behaviour of supporters towards Raheem Sterling during our match against Manchester City on Saturday.

“Our investigations into this matter are ongoing. We are fully supporting the police investigation and any information we gather will be passed on to them.

“Chelsea Football Club finds all forms of discriminatory behaviour abhorrent and, if there is evidence of ticket holders taking part in any racist behaviour, the club will issue severe sanctions, including bans. We will also fully support any criminal prosecutions.”
