FIGC President Carlo Tavecchio condemned Roma ultras for insulting the mother of killed Napoli fan Ciro Esposito.
There were several banners and chants during Saturday’s 1-0 result at the Stadio Olimpico accusing Antonella Leardi of trying to make money from the death of her son.
Esposito was shot by a Roma fan ahead of the Coppa Italia Final in May 2014 and later died of his injuries.
Leardi has put forward a message of peace and asked to get violence out of football, so to see her attacked in this way caused consternation.
“I show my solidarity with Mrs Leardi, who was gravely offended when feeling the deepest pain by those banners at the Stadio Olimpico in Rome,” said Tavecchio.
“I condemn what happened and the authorities have already shown an interest in the incident.
“It is important to clarify how it was possible for this to happen in a stadium that had a maximum security presence.”
Any banners that are not authorised should not be allowed into the stadium during Serie A games, let alone one that was considered high risk.
Roma risk a large fine and seeing some or all of the stadium closed for future matches.
