Police have arrested six people regarding alleged public order offences after a banner attacking Bolton Wanderers forward Marvin Sordell was unfurled at Millwall's New Den stadium.
Sordell was racially abused by a 13-year-old boy, who has since been banned from the ground, during Bolton's 2-1 defeat at Millwall last month.
The banner was unveiled in the home section of the New Den during the Lions' 2-1 win over Derby this afternoon.
A Metropolitan Police spokesman said: "Six males were arrested during the game at Millwall in relation to a banner being unfurled at the game.
"They remain in custody at this time. The banner on display today was swiftly removed by Millwall staff."
Millwall have yet to comment on the arrests.
