The Garda say that the National Economic Crime Bureau are investigating allegations of match-fixing at Bray Wanderers.
The fraud squad confirmation came off the back of reports that 5 games are now being probed.
The FAI launched an investigation into the 5-0 friendly loss to Waterford last week.
Four other games are now being linked to the investigation. The IRN-BRU Cup 2-0 defeat away to Elgin City, last month’s 2-1 SSE Airtricity League win over Drogheda United and the two home games against Finn Harps — a 5-3 win in March and a 3-2 defeat in July.
Bray Wanderers return to action tonight by welcoming Limerick to the Carlisle Grounds.
In a statement the Garda press office said: "The Garda National Economic Crime Bureau are currently investigating this matter. As this is an ongoing investigation we are unable to comment any further".
