Montreal police say they have arrested a fifth member of the force as part of an internal investigation.
The unidentified officer has been suspended without pay but has not been charged.
Four other officers were arrested July 7, with two facing various charges including perjury, attempting to obstruct justice, soliciting and obtaining sexual services.
Police say all five arrests are linked to the same investigation.
The probe began in December after irregularities were noticed with regard to the control of informants.
