The Jakarta Police are investigating suspicions of corruption surrounding the renovation of 119 schools across the capital last year.

“We’re going to question people related to the renovation project,” Jakarta Police Special Crimes chief Sr. Comr. Adi Deriyan said on Monday as quoted by tempo.co.

The project took up Rp 191 billion (US$13.3 million) from the capital’s 2017 budget, which was disbursed through the Jakarta Education Agency (Diknas).

Investigators believe that the cost of the project had been inflated for personal gain. The list of people they plan to question in the case includes several Diknas officials, as well as representatives from the developer and consulting company tasked with carrying out the renovations, Adi said.

 “We’ll also summon several school principals and we’ll need an explanation from the city inspectorate. We need to know where the renovations were being conducted,” he added.
