The Serie A side tweeted an image of the messages - including details of the account - and confirmed they had reported the incident to the police.

The public denunciation was met with widespread appreciation on Twitter.

It comes after anti-discriminatory body Fare said Italian football authorities and their disciplinary systems to combat racism were not fit for purpose.

Fare executive director Piara Powar added "the rot is deep" and "no-one is taking the issue seriously", but Serie A insisted it was "seriously and constantly engaged in activities against racism".

AC Milan launched an anti-racism task force at last weekend's derby against Inter, christened the 'Derby Against Racism', in response to recent racist incidents.

Inter striker Romelu Lukaku had been subjected to monkey chants by Cagliari fans during a Serie A game on 2 September, however Cagliari were cleared of racist chanting.
