Arsenal to warn staff not to wear team colours after West Ham fan assaults a member of their media team

ARSENAL will be advising their staff not to wear team colours when attending away matches after a member of the club’s media team was involved in a minor assault at the hands of a West Ham fan at the London Stadium on Saturday.

Reports after the Hammers’ 5-1 defeat suggested that an Arsenal TV cameraman was approached by the opposition fan as he headed through the stadium concourse to conduct post match player interviews in the tunnel.

The employee has not suffered any serious harm and both Arsenal - who have a close relationship with their Premier League counterparts - are working together with West Ham and the police to find the culprit.

Violent scenes at the London Stadium have marred West Ham's move to the £323m venue after making the switch from the historic Upton Park site.

Crowd trouble during West Ham's win over Chelsea in the fourth-round of the EFL Cup lead to police making seven arrests.

The club promptly issued a statement to "unreservedly condemn" fans' behaviour and explain that they would be working to identify those supporters involved.

Without a satisfactory radio system initially installed at the London Stadium, the club experienced a number of 'teething problems' before Metropolitan Police Officers were stationed inside the ground for the first time in the game against Stoke in November.

The Hammers are coming down hard on any supporters who are involved in violent clashes and have vowed to hand out life bans for up to 200 fans.

West Ham have been contacted for comment.
