Istanbul's prosecutor's office issued warrants for a total of 35 people over their suspected links to the renegade army units that tried to overthrow President Recep Tayyip Erdogan on July 15, Hurriyet said.
Eighteen of the suspects had already left the country and eight others were still being sought, NTV said.
The government has accused US-based Turkish Muslim cleric Fethullah Gulen of masterminding the putsch, a claim he vehemently denies.

Ankara has embarked on a purge of tens of thousands within the police, judiciary, education, business and the media to rid the country of what Erdogan calls the "virus" of Gulen's influence.
The journalists arrested on Tuesday were accused of pro-Gulen propaganda, Hurriyet said.
Several other journalists are already in custody awaiting trial, including veteran journalist and writer Nazli Ilicak.
