Turkey has suspended some 12,800 police officers over their alleged links to U.S.-based Muslim cleric Fethullah Gulen.
Turkish national police said on October 4 that more than 2,500 of the suspended officers were police chiefs.
Tens of thousands of people have been dismissed or suspended from government jobs since July's failed coup, while some 32,000 people have been arrested in connection with the coup bid.
The Turkish government accuses Gulen of masterminding the coup, which he denies.
Ankara in turn rejects claims that it is using the coup as an excuse to get rid of its opponents.
On October 3, the government announced that a state of emergency imposed shortly after the coup attempt would be extended by three months when it expires on October 19.
The measure allows the president and cabinet to rule by decree.
