East Ham has pledged to banish any supporter found guilty of attacking visiting journalists during their 2-1 loss to Eintracht Frankfurt on Thursday night.
Two ARD radio reporters have claimed they were attacked by West Ham fans while broadcasting live following Michail Antonio’s 21st-minute equalizer.
Reporters Tim Brockmeier and Philipp Hofmeister said they were punched and their headphones ripped off by fans.
West Ham will review CCTV and work with police to ensure the offender is given an indefinite ban.
Brockmeier and Hofmeister were seated in the back row of the press box with fans directly behind them and moved on at half-time.
In a statement, a West Ham spokesperson said: “The club is aware of the incident and will endeavor to identify the culprit. In line with our zero tolerance approach, anyone identified will have their details passed to the police.
“They will be banned indefinitely and will not be able to enter the London Stadium and travel with the club. There is no place for this kind of behavior.
Hofmeister said on the live broadcast: “If you constantly have the feeling that something might come from behind, a punch or something. My English football dreams were shattered.
After the match, Hofmeister tweeted: “We are fine. Best wishes to all West Ham supporters who love football and respect their opponents.
