JERUSALEM (JTA) — Israeli police have detained 30 senior officials accused of corruption.

The officials, who where detained Wednesday morning after a yearlong investigation, include deputy government ministers and senior officials in government ministries, in addition to mayors, heads of NGOs, union chiefs and officers in government corporations. Documents and computers were also confiscated from the officials.

The officials are accused of accepting bribes and illegally funneling funds to NGOs, according to reports. In exchange, the NGOs allegedly gave jobs to people close to the officials.

The names of the officials were to be revealed Wednesday.

“The covert investigation revealed a calculated method wherein the suspects and their representatives unlawfully transferred, using their powers as public officials, large sums of public funds to [various] bodies and authorities, in exchange for large benefits for them or their associates, including appointments, payments and more,” a police statement said, according to the Times of Israel.
