Three of the people arrested late last year in a major case involving bribery, fraud and money laundering were current or former employees of a security agency, the police announced on Tuesday after the scope of a gag order on the case was reduced.

Police believe the suspects, seven in all, tailored security agency purchase orders in a way that ensured certain civilian companies would win the contracts. These orders are suspected of being tailored “in exchange for bribes to the agency employees on an enormous scale,” police said in a statement.

All the suspects were held in jail for several weeks after their arrest, but now have all been released with various restrictions. The investigation into the case is ongoing.

In May, after another gag order was lifted, the Justice Ministry department responsible for investigating police misconduct announced it was charging two employees of the Shin Bet security service with stealing public funds. The alleged theft was uncovered during an internal audit of the agency, which then asked the Justice Ministry to investigate.
