ANKARA (Reuters) -Turkey's football federation (TFF) will launch disciplinary action against referees found to have bet on football matches after discovering that hundreds of them had betting accounts, its president said on Monday.

TFF President Ibrahim Haciosmanoglu said a federation probe — based on data from state institutions — revealed that 371 of 571 active referees in Turkey's professional leagues had betting accounts, and 152 of them were actively gambling.
