Turkish police on Wednesday detained 49 former shareholders of the now-closed Islamic lender Bank Asya out of 68 for whom warrants were issued over alleged links to the Gülen group, the state-run Anadolu news agency reported.

The operation, spanning nine provinces, was initiated by a prosecutor’s office investigating former shareholders who had authority to elect the executive board and make trade-related and administrative decisions. Two of the shareholders are reported to be abroad.

The bank was recently declared bankrupt by a regulatory body.

The Savings Deposit Insurance Fund (TMSF) had taken over management of Bank Asya and took control of 63 percent of its privileged shares, enough to name the board, in February 2015. New board members, a general manager and deputy general managers were immediately appointed.

In the aftermath of a coup attempt on July 15, 2016, the government closed down Bank Asya on the grounds that it was linked to the Gülen group, accused by the government of masterminding the putsch.

The movement denies any involvement in the failed coup.
