Thirty-two suspects were captured on Tuesday in an investigation into infiltration by the terrorist group Revolutionary People’s Liberation Party-Front (DHKP-C) in several municipalities in Istanbul, according to Daily Sabah.

Investigators say the group took over a textile company and through it, participated in tenders by municipalities that awarded the company through irregular practices, essentially funding the terrorists.

The captured suspects include former employees of the municipalities of Ataşehir, Maltepe, Sarıyer and Şişli. All worked there between 2014 and 2016, the period the investigators focused on.

Authorities say some suspects were part of the “financing committee” of the DHKP-C. Doğan K. and Yunus B., two of the suspects, were identified as part of the committee that sought financing from municipalities.

Investigators also say that the suspects were involved in an illegal labor movement linked to the DHKP-C, which took over a textile company after the latter had a mass layoff and failed to pay wages. The company, now controlled by the DHKP-C, secretly participated in public tenders at Sarıyer and Şişli municipalities between 2014 and 2015. A probe into the tenders discovered irregularities and the company won tenders thanks to these irregularities, profiting from overpriced sales of goods to municipalities. Police said six other suspects were implicated in the investigation and two were incarcerated earlier for other offenses while others were abroad.

The suspects were caught in operations conducted in 31 locations, including in Istanbul, the northwestern city of Bursa and the northern city of Samsun.
