Three men in their 30s who were arrested as part of a garda operation investigating suspected match-fixing in the League of Ireland have been released without charge.

A file is being sent to the DPP.

Members of Interpol's Match-Fixing Task Force supported today's operation. Today's arrests brings to 14 the number of people questioned as part of the investigation.

Operation Brookweed began three years ago in 2019 after the FAI and UEFA made reports of suspected match-fixing to gardaí.

As part of the investigation, which is being led by the Garda Anti-Bribery and Corruption Unit, three men in their 30s were arrested today during what gardaí describe as a "day of action".

The three people arrested today were being held on suspicion of conspiracy to defraud before their release.

Gardaí say a fourth man was arrested in the north west last week and was later released without charge.

In May of this year, ten men were arrested in Dublin, Limerick and Cork and questioned in connection with the investigation, but all were later released without charge.

In a statement, the FAI said it notes the latest development and that it and UEFA remain committed to a zero tolerance policy on match fixing.

In what is an indication of the scale and seriousness of this investigation, gardaí said that today's operation was supported by officers attached to Interpol's Match-Fixing Task Force who travelled here from the Interpol Headquarters in Lyon in France.

Gardaí have also renewed their appeal for anyone with information about match fixing in the League of Ireland to contact them in confidence on their Bribery and Corruption Confidential Reporting line – 1800 40 60 80, the Garda Confidential Line 1800 666 111 or to their local garda station.

Detective Superintendent Catharina Gunne of the Garda National Economic Crime Bureau said the units focus was to disrupt criminality which undermines confidence in sport.

"Match-fixing and corruption is a threat to all sports at all levels and undermines public confidence in the fairness of sport. It can allow organised crime to infiltrate sport in order to use it to make illicit gains or launder proceeds of crime," she said.

"The Anti-Bribery and Corruption Unit will take proactive action where necessary to disrupt such criminality. Match-fixers prey on young and vulnerable players in order to corrupt them for their ends.
