Italian police have seized documents from Italian and foreign clubs, including 18 in the top league, as part of an investigation into tax evasion and money laundering involving player transfers, Reuters reports.

Apart from the Series A  teams, 11 B league teams and 12 from the lower divisions are being investigated, according to a police spokesman. The probe also includes 12 player agents. The names of the clubs involved have not been disclosed, although judicial and police sources informed Reuters that clubs SS Lazio and Juventus FC are among those under investigation.

A Naples court ordered the searches as part of an investigation into criminal conspiracy, international tax evasion, money laundering and invoice falsification.
