A second Rangers fan has been arrested for allegedly racially abusing Celtic player Scott Sinclair.

A 27-year-old man has been detained in connection with an alleged offence under the Offensive Behaviour at Football and Threatening Communications Act.

The supporter has been reported for making a monkey gesture during the Old Firm match.

The man is expected to appear at Glasgow Sheriff Court on Friday.

A report will be submitted to the procurator fiscal.

Police arrested another man on Monday for making the same gesture during the game, which Celtic won 5-1.
