A 74-year-old has been arrested on suspicion of throwing a banana at the referee during Port Vale's 2-2 League Two draw at Wimbledon on Thursday.
Police viewed television footage of the incident, which took place in the 26th minute of the first half, before arresting a Wimbledon-supporting pensioner. He has been released on bail to report to police at a later date.
Football intelligence officer Sam Cunningham said the incident was not considered to be racist. He said: "We saw the banana thrown onto the pitch and then reviewed television coverage.
"It appears a supporter was angered by a decision by the referee and aimed a banana at him. It was not aimed anywhere near any player."
