A 20-year-old man arrested over the alleged abuse of an Oldham footballer at Anfield has been released on bail.
Merseyside Police said the suspect, who was arrested on suspicion of a racially aggravated public order offence, has been released pending further inquiries.
The force launched an investigation following an incident at Liverpool’s Anfield stadium on Friday night.
Oldham Player Tom Adeyemi, 20, appeared to have been visibly upset by an individual’s comments made during the third-round FA Cup tie.
He is thought to have taken offence to something shouted out late on in the game, which the home side won 5-1.
The allegations come in the aftermath of striker Luis Suarez’s eight-match ban for racially abusing Manchester United defender Patrice Evra.
Despite reassurance from his team-mates, as well as Liverpool captain Steven Gerrard and striker Dirk Kuyt, right-back Adeyemi seemed close to tears.
There then appeared to be a discussion between the fourth official and a police officer down by the tunnel while the game was continuing.
It is understood Adeyemi gave a statement to police after the match.
In an initial statement, police said: “The force and Liverpool Football Club are investigating following an incident that occurred during the second half of the game.
“The aim of the investigation is to establish the full circumstances surrounding the incident to ascertain if action needs to be taken.”
It was then confirmed on Saturday evening that a 20-year-old man had been arrested in connection with the incident.
Liverpool Football Club issued a statement on Sunday stressing its commitment to tackling discrimination and expressing its regret over the incident.
It said: “All of us are deeply sorry for what happened on Friday night and our players and our Club pass on our sincere regrets to Tom Adeyemi for the upset and distress he suffered.”
The statement added: “Our supporters are renowned throughout the world for their outstanding commitment, passion and fairness.
“They are drawn from nationalities across the globe with widely diverse backgrounds and heritages. The actions of any one individual do not represent our fans.”
The club has provided police with CCTV and photographs of what they believe is the relevant area of the stadium.
Footage filmed by in-house crews and ticketing information has also been handed over and matchday stewards in that part of the stadium have given statements.
Oldham manager Paul Dickov said: “He is a placid boy, a kid who has been well educated with a fantastic temperament and has been with us since the end of August and I’ve never seen him raise his voice.
“For him to react like that it is obvious something has been said but what has been said I don’t know because I’ve not had a chance (to ask) – I was too busy praising my players.
“He is fine now. He has calmed down. He is a laid-back kid who just gets on with business.”
