A person with knowledge of the case, who is not authorized to speak publicly on the issue, told The Associated Press that police officials searched the facilities for about an hour.

According to the same person, the investigation is targeting several contractor firms linked to Paris Saint-Germain.

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 soccer 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.
