The full-back, 20, had to be consoled by team-mates and Liverpool players 10 minutes from the end of this FA Cup third-round tie after a comment shouted from the Kop.

Adeyemi was walking back into position after a tackle when a supporter wearing a Luis Suarez T-shirt is alleged to have shouted disgusting racist insults.

An eye witness, who later gave evidence to club officials and the police, claimed he heard a single voice shout: "You f****** black b******."

Adeyemi, on loan from Norwich, also gave a statement to police before heading straight on to the team bus. It is understood he also claimed he had been called a "black c***."

Other witnesses insist he was also subject to shouts of "Manc b******".

That stems from the fact fans are incensed at the handling of the Suarez race row with Manchester United's Patrice Evra, when the Uruguayan received an eight-game ban for calling the Frenchman a 'negro.'

Merseyside Police said: "We can confirm no one has been arrested on suspicion of racially aggravated behaviour.

"However, the Force and Liverpool FC are investigating following an incident that occurred during the second half.

"The aim of the investigation is to establish the full circumstances surrounding the incident to ascertain if any action needs to be taken."

Oldham boss Paul Dickov said: "I have not spoken to Tom about it.

"But I will say I know the kid and something has been said. He is a placid boy who has been well educated and has a fantastic temperament.

"So for him to react like that it's obvious that something has been said."
