Seventeen active-duty officers and one retired officer were detained in 13 Turkish cities Friday in the second wave of detentions in the probe into an alleged coup plan against the government, broadcaster CNNTürk reported.

The new detainees will be brought to Istanbul.

According to the report, the chief of gendarmerie in the province of Konya is among the detainees.

Around 50 active-duty and retired military officers were detained Monday; 31 were charged later in the week with plotting to overthrow the government.

The investigation stems from a report in Taraf daily alleging the existence of the “Balyoz” (Sledgehammer) plan, which, the daily said, aimed to trigger a military takeover by creating chaos through mosque bombings and assassinations and shooting down a Turkish fighter to show the weakness of the ruling Justice and Development Party.
