Arrests were made over interference with refereeing procedures, among other accusations, Turkish justice minister says.

The head of Turkiye’s football refereeing body and six other people have been arrested over accusations of interference in refereeing procedures, Justice Minister Akin Gurlek said.

“Claims regarding interference in the formation of referee classifications, assignments, scoring and appointment processes, as well as rule examinations, have been investigated,” Gurlek wrote in a social media post on Tuesday.

Ferhat Gundogdu, the president of the refereeing body, and his deputy were among those arrested.

Gurlek said searches had been carried out at the suspects’ “residences, workplaces and offices”.

“We will steadfastly continue the fight for clean football so that claims undermining trust in Turkish football are clarified, those responsible are held accountable before the law, and football is remembered for the effort, struggle, and sportsmanship on the field,” Gurlek added.

A year ago, the Turkish Football Federation (TFF) suspended 149 referees on charges of involvement in an illegal betting scandal.

The TFF investigation found that 371 out of the country’s 571 referees officiating in the professional leagues had betting accounts and 152 of them actively placed bets.

Some 29 people were arrested in the sprawling scandal, including 14 footballers, one of whom was Fenerbahce’s international midfielder Mert Hakan Yandas.

Authorities suspended more than 1,000 players, including 25 from the first division.

However, Gurlek did not draw any link between last year’s betting scandal and the current investigation.
