Turkey's state-run news agency says police have detained dozens at Turkey's banking regulatory agency and at one of Istanbul's largest universities as part of an investigation into the July 15 abortive coup which killed over 270 people.

Anadolu Agency said 29 auditors at the Banking Regulation and Supervision Agency were detained early Monday for allegedly conducting "irregular probes" in 2013 into businessmen and foundations that are close to the government.

Meanwhile, detention orders were issued for 62 academics working at Istanbul University as part of the same investigation. Police detained 44 of them Monday morning.

Turkey accuses U.S.-based cleric Fethullah Gulen of masterminding the coup and has launched a massive crackdown on his movement, detaining more than 40,000 people and dismissing tens of thousands from government jobs.
