BERN, Switzerland — Swiss prosecutors are investigating five clubs in Switzerland as part of European soccer’s biggest corruption scandal.

Jeannette Balmer, a spokeswoman for the federal prosecutors’ office, said Wednesday that Swiss second-tier clubs FC Thun, Gossau, Wil 1900 and Schaffhausen along with third-tier Fribourg are under investigation.
Balmer said authorities are examining the second leg of the 2008-09 season and the first leg of the 2009-10 season. The Swiss soccer federation says a total of 17 league games and two test games were affected.
Switzerland is one of nine countries named in European soccer’s corruption scandal, which was uncovered during a German-led betting scam probe.
