Turkish authorities arrested 57 more people suspected to have links to the failed military coup last year.
The Anadolu news agency, which is pro-government, claimed the group had been apprehended as they planned some sort of operation against the Stock Exchange in Istanbul.
The agency claims more than 100 arrest warrants have been issued, with the arrests having taken place in six provinces across Turkey.
The government under President Erdogan has arrested more than 110,000 people since the coup attempt in July 2016 in a widely-condemned crackdown.
It has pinned the blame for the coup on cleric Fethullah Gulen, a prominent critic of Erdogan and his regime.
