Strathclyde Police are now involved in the investigation into the Stephen Maguire v Jamie Burnett match at last December's UK Championship.
This match is the subject of an investigation by the Gambling Commission following a heavy volume of bets for Maguire to win 9-3, which was the final result.
And the Glasgow Evening Times reports that the investigation has moved a step further.
A spokeswoman for Strathclyde Police told the newspaper: "After consultation with the Procurator Fiscal's Office, our Economic Crime Unit is carrying out inquiries."
The police are likely to interview both players as well as tournament staff and other parties.
Maguire plays Burnett again in the Betfred.com World Championship at the Crucible next week.
