French police raided Paris Saint-Germain’s academy on Thursday, acting on a request from the body responsible for collecting taxes.

A person close the case, who is not authorized to speak publicly on the issue, said that police officials searched the facilities for about an hour.

According to the source, the investigation is targeting several contractor firms linked to the Ligue 1 giants.

The URSSAF, the agency for collecting and distributing social security contributions, did not immediately respond to an email seeking comment.

In a separate case last month, police investigating suspected tax fraud linked to the football industry raided PSG headquarters and the homes of players Angel Di Maria and Javier Pastore.

The national financial prosecutor’s office opened an investigation in December after ‘football leaks’ reports allegedly detailed tax arrangements by top players, coaches and clubs.
