Liverpool face more race disgrace after their FA Cup win over Oldham Athletic.
Oldham's on-loan Norwich City youngster Tom Adeyemi was left in tears after allegations of vile abuse.
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.
The Sun says 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******".
Merseyside Police said: "We can confirm no one has been arrested on suspicion of racially aggravated behaviour.
"The aim of the investigation is to establish the full circumstances surrounding the incident to ascertain if any action needs to be taken." "However, the Force and Liverpool FC are investigating following an incident that occurred during the second half.
