The betting scandal first erupted on 27 October and focused on referees.
A five-year TFF investigation found 371 of 571 match officials in Turkey held betting accounts, with 152 of those actively gambling.
While some had only bet once, 42 had bet on more than 1,000 football matches – with one official was found to have placed 18,227 bets.
Of these 152 referees, seven were top-flight referees and 15 were top-flight assistant referees.
Shortly after the TFF’s announcement in October, Istanbul’s chief criminal prosecutor said the statement would be treated as a formal criminal complaint and that ongoing investigations would be expanded.
The investigation then moved beyond match officials.
7 November: Prosecutors order the detention of 21 people on suspicion of “manipulating match results” and “sharing misleading information online”.
10 November: Eight suspects – including the president of Super Lig side Eyupspor Murat Ozkaya – is arrested.
10 November: The TFF says it has referred 1,024 players to the disciplinary board for betting violations. So many players are suspended that the TFF asks Fifa for an extra 15 days in addition to the winter transfer window so clubs can deal with squad shortages.
13 November: 102 players from the Super Lig and the second-tier 1 Lig receive bans ranging from 45 days to 12 months. Among them are Baltaci (nine months) and Eren Elmali (45 days).
18 November: 282 third tier players are issued with bans.
20 November: A further 638 fourth tier and unattached players are banned.
