Uefa has vowed to seek the “harshest of sanctions” for any players or clubs found guilty in biggest the match-fixing scandal ever to hit Europe.
It emerged at the end of last week that about 200 football matches were under investigation – at least three of which were in the Champions League and 12 in the Europa League.
On Thursday, police carried out about 50 raids in Germany, the UK, Switzerland and Austria, making 17 arrests and seizing cash and property.
The matches under investigation were played in Germany, Belgium, Switzerland, Croatia, Slovenia, Turkey, Hungary, Bosnia-Herzegovina and Austria.
Uefa general secretary Gianni Infantino said: “We will continue our battle against any form of corruption in European football with a mission of zero tolerance.
“Uefa will be demanding the harshest of sanctions before the competent courts for any individuals, clubs or officials who are implicated in this malpractice, be it under state or sports jurisdiction.”
Prosecutors believe a 200-strong criminal gang has bribed players, coaches, referees and officials to fix games and then made money by betting on the results.
The investigation is being carried out by German authorities and supported by Uefa.
