A former Oklahoma police officer is facing charges of sexually assaulting at least four women while he was on duty and in uniform, according to KFOR-TV.

Justin Rahlf—who resigned from the McLoud (OK) Police Department in September—was reportedly booked into Pottawatomie County's jail on charges of "forcible oral sodomy and indecent exposure," ABC News said.

"The McCloud Police Department received credible information that one of our former officers may have engaged in inappropriate and possible criminal conduct of a sexual nature while on duty," said McLoud Police Chief Tom Pringle.

Records reportedly show that at least four victims have so far come forward with allegations dating back to 2016.

Rahlf has subsequently resigned from the McLoud Police Department.

The investigation remains ongoing.
