The sale of San Siro to Inter and AC Milan is now at the center of a fresh judicial investigation in Italy. In the early hours of the morning, the Guardia di Finanza - Italy’s financial police - carried out a series of searches at Milan City Hall, the offices of M-I Stadio, and the homes of several former officials and executives linked to the deal.

The investigation, launched at the request of prosecutors Giovanna Cavalleri, Paolo Filippini and Giovanni Polizzi, is focused on allegations of bid rigging.

Among those under investigation are former city councillors Giancarlo Tancredi and Ada Lucia De Cesaris, along with Milan’s city director general Christian Malangone. According to La Repubblica, the list of individuals under investigation also includes Giuseppe Bonomi, Alessandro Antonello and Mark Van Huukslot.

The probe also involves Simona Collarini, the former head of Milan’s urban regeneration department and the public official in charge of the stadium procedure at the time, as well as consultants Fabrizio Grena and Marta Spaini, who are understood to have worked respectively with Inter and Milan.

Searches were also carried out at the premises of third parties, and several mobile phones were seized. Investigators are now expected to examine chats, emails and other digital communications that may overlap with evidence already gathered in the wider urban planning investigation that shook Milan last summer.

That earlier case had led to several arrests, although those measures were later overturned by both the Review Court and Italy’s Supreme Court of Cassation. Tancredi, Malangone and De Cesaris are already among those being examined in that broader investigation.

The latest line of inquiry reportedly stems from a number of complaints filed with prosecutors, including one submitted by former deputy mayor Luigi Corbani and music promoter Claudio Trotta, both linked to the Sì Meazza campaign group.

At the heart of the case is the transaction through which the City of Milan received €197 million from the sale of the Meazza stadium to Inter and Milan. Prosecutors are trying to determine whether the process may have ended up favoring private interests at the expense of the public interest.

Investigators are also examining whether Italy’s stadium law may have been used to support a broader redevelopment and urbanization project surrounding the area.
