Gavin Kirkham was arrested on Monday after being identified on social networking websites following the game last Wednesday, and he was held on suspicion of a racially aggravated Section 4a Public Order Act offense before being bailed until Nov. 29.
Chelsea were keen to stress that the 28-year-old Kirkham holds no membership with the club.
“Chelsea Football Club has banned a 28-year-old man from Stamford Bridge pending the conclusion of a police investigation into a possible racially aggravated public order offense,” a Chelsea spokesman said.
“The man is not a current Chelsea FC season ticket-holder or member. Chelsea is co-operating fully with the police as they carry out their investigation.”
The man was arrested on Monday after attending a West London police station by appointment.
