Brigadier air force general Bekir Ercan Van was detained along with over a dozen lower ranking officers yesterday at the air force base of Incirlik in Turkey's southern Adana province, newspapers including the Hurriyet daily said.
They were now being interrogated by investigators, the reports added.
A Turkish official told AFP yesterday that Ankara suspected Incirlik was used to refuel military aircraft "hijacked" by the coup plotters on Friday night.
But the Turkish authorities imposed a security lockdown on the base in the wake of the coup, allowing no movement in or out, the US consulate in Adana said.
Meanwhile, operations from the Incirlik air base were suspended because of the closure of the airspace used for the missions, Pentagon spokesman Peter Cook said in a statement.
