An investigation was launched after Friday night's Liverpool v Oldham FA Cup third-round game.
Merseyside Police said a 20-year-old man from Aintree, Merseyside, was arrested on suspicion of a racially aggravated public order offence.
The man is being held in custody and being interviewed by detectives.
The game was stopped briefly while Adeyemi - on loan from Norwich - alerted referee Neil Swarbrick to the incident.
On Saturday evening, Liverpool issued a statement, saying: "Liverpool Football Club continue to work closely with Merseyside Police to establish all the facts surrounding the incident that occurred during last night's game.
"We take this matter extremely seriously and have today provided the police with the evidence we currently have available to us."
The incident compounds a difficult few weeks for Liverpool, who were without Luis Suarez for the match against the Oldham as the striker serves an eight-match ban for racially abusing Manchester United defender Patrice Evra at Anfield in October.
