British police launched an investigation Monday after two England internationals were subject to abuse on social networking site Twitter.
Asley Young and Ashley Cole were targeted after missing penalties in England's Euro 2012 quarter-final loss to Italy on Sunday.
A Metropolitan Police spokesman said: "We are aware of alleged racist comments on Twitter following last night's England game and have launched an investigation.
"The allegation was made to MPS on 25 June by a member of the public relating to comments on a Twitter account supposedly based in London.
"No arrests at this early stage.
