British police confirmed that a man arrested over an alleged racist gesture made during Liverpool's FA Cup fourth-round victory over Manchester United has been released on bail.
An image of a man apparently making a monkey gesture in the stands was widely distributed on social networking websites, and a number of complaints were made to police after the match which ended in a 2-1 win for Liverpool.
The man from the North Wales area was held after the game at Anfield.
A Merseyside Police spokeswoman said: "A 58-year-old man from North Wales who was arrested on suspicion of a racially aggravated public order offence yesterday (Saturday) following the Liverpool and Manchester United match has been released on police bail pending further inquiries."
It was the first game between the rivals since the eight-match ban imposed on Liverpool striker Luis Suarez after the FA found him guilty of racially abusing United defender and captain Patrice Evra.
Before the match the stadium announcer warned supporters that racist and homophobic behaviour would not be tolerated.
It is understood that home supporters found guilty of such offences inside the ground would be subject to life bans from the club.
