Police are investigating allegedly racist comments made against footballer Ashley Cole on Twitter, just days after his team-mate John Terry was cleared of racism. A user, believed to be a man from Derbyshire, referred to the Chelsea star as a "choc ice" on the site. Manchester United defender Rio Ferdinand then replied: "I hear you fella! Choc ice is classic hahahahahaha!!". Derbyshire police said it was investigating the original tweet after receiving complaints from members of the public. The incident comes after the Chelsea captain, John Terry, was cleared of a racially aggravated public order offence at Westminster magistrates court last week.
