The IGP is to be handed over investigations into the alleged sexual harassment of female parliamentary housekeeping staffers by their superiors.
After inspecting the relevant files, the attorney general had advised that there was adequate evidence that permitted a probe.
A spokesman for parliament said all those files would be handed over to the police chief in a matter of days.
Complaints by more than 20 staffers
The assistant housekeeper and another officer have been suspended following complaints by more than 20 female staffers that they were sexually harassed.
An internal inquiry took place first and several other officers have been mentioned as suspects.
