West Ham fans arrested over Chelsea match race offences
Two West Ham fans have been arrested over racially-aggravated public order offences following Sunday's Premier League match against Chelsea.
The men have been released on bail until later this month, the Met said.
The arrests come as the police force launched a separate investigation after coins were thrown when Frank Lampard scored his 200th goal for Chelsea.
As Lampard celebrated with substitute John Terry, objects were thrown from the crowd in their direction.
The incidents took place as the two sides clashed in the London derby match at Stamford Bridge in west London, which Chelsea won 2-0.
Officers are studying CCTV footage from the stadium and no arrests have been made as yet over the coin throwing.
The Football Association said it would liaise with the police and the two clubs involved.
Nine years ago England midfielder Lampard, who moved to Chelsea from West Ham in 2001, was hit by a coin during a League Cup tie between the clubs.
