The match, between Arlesey Town and Potton United, in the Spartan South Midlands Football League (SSMFL) Premier Division, ended after 61 minutes after the incident on Tuesday evening.

The alleged comment was said to have been directed towards Arlesey Town goalkeeper coach, Ishmael Mills.

In a statement, Potton United "categorically" denied "any racist remark was made" and said they would be assisting authorities with any investigation.

The club said the comment was captured on a Veo sports camera - used by teams to record fixtures - and they would happily share footage with authorities.

Meanwhile, Arlesey Town said the incident has "left a stain" on non-league football.

"Arlesey Town Football Club will not tolerate racism in any way, shape or form," the club said.

It said the club will be supporting the relevant authorities with "witness statements and video evidence that supports the club's position".

The SSMFL Premier Division sits in Step 5 of the English football league system, comprising teams from Bedfordshire, Essex, Hertfordshire, Buckinghamshire and Greater London.

The league, Bedfordshire Football Association and Bedfordshire Police have been approached for comment.
