ISTANBUL- Turkish prosecutors have begun charging some of Prime Minister Recep Tayyip Erdogan's closest allies in a huge graft scandal he has responded to with a spectacular purge of the police.
Erdogan has said he is battling "a state within a state" and described the corruption probe, which comes ahead of crucial March polls, as a smear operation.
Media reports on Friday said prosecutors had begun handing out corruption indictments to some of the 89 suspects arrested three days earlier, with the first eight formally arrested and placed in pre-trial detention.
They are accused of numerous offences including accepting and facilitating bribes for development projects and securing construction permits for protected areas.
The remaining detainees were appearing in court Friday after being interrogated by police, according to local media.
The crisis erupted Tuesday when police made the arrests in a series of dawn raids, one of the most brazen challenges to Erdogan's 10-year rule.
Among the suspects detained were the sons of Interior Minister Muammer Guler, Economy Minister Zafer Caglayan and Environment Minister Erdogan Bayraktar, along with the chief executive of state-owned Halkbank, Suleyman Aslan, and construction tycoon Ali Agaoglu.
The environment minister's son has since been released, but the other two ministers' sons are still being held for questioning, the Dogan news agency reported.
The Hurriyet daily said 15 other suspects had also been released, but there was no official confirmation.
The crisis has rattled the stock market and sent the Turkish lira to an all-time low.
Since the scandal broke out, Erdogan has sacked dozens of police officials, including the Istanbul police chief, for cooperating with the investigation without permission.
