“Such behaviour is clearly totally unacceptable and will not be tolerated.

“It would be inappropriate to comment further while the situation is ongoing other than to confirm the club will follow due process in any and all cases of this nature.”

The statement has been criticised for failing to make explicit reference to the incident or racially abusive remark, but Liverpool say they felt it would be “inappropriate to comment further”.

Merseyside Police superintendent Paul White added: “We want to reassure the public that we can act on incidents using British Law and we will take action.”

Spanish football journalist and pundit Guillem Balague also used Twitter to plead with Liverpool fans to ‘look after’ his ‘beautiful city’.

He wrote: “Honestly? LFC fans!! I know it’s only some of you but please… Do you need to do all this? Do you? Is that what you do home? Come on, guys and girls, look after my beautiful city. Or tell the others to look after it…. Please.”

Many Liverpool fans have condemned the video on social media, urging the club to issue stadium bans.

“Please identify this man and refuse him entry from the stadium tomorrow, he is an embarrassment to our great European following,” wrote @TheAnfieldTalk in a post directed at Moore and Liverpool’s supporter liaison officer that was retweeted 1,700 times.
