The alleged incident took place at the end of the Latics' FA Cup third round tie against Liverpool at Anfield.
Adeyemi was visibly upset after a fan in the Kop end of the stadium was thought to have shouted a racial slur at the 20-year-old.
Merseyside Police arrested the man, believed to be from the Aintree area of the city, on Saturday night after launching an investigation.
