Former Lazio captain Giuseppe Signori has arrived for questioning by judicial authorities probing his alleged role in the latest Italian match-fixing scandal.

Signori was one of 16 people arrested across Italy last week as part of an inquiry focused on 18 matches mostly in Serie B and C. However, key suspects in the case have reportedly divulged information about top-division games that were fixed.

Signori, who retired in 2006, allegedly led a group of bettors in Bologna that had a direct impact on the match-fixing.

The ANSA news agency reports that Signori's lawyer, Silvio Caroli, says his client intends to respond to the questions posed by the judge leading the preliminary investigation.

Signori has thus far refused to comment on the inquiry.
