A provincial police staff sergeant is facing charges following an investigation by the force's professional standards bureau.

Investigators say the officer was arrested Tuesday and charged with single counts of assault and sexual assault in relation to an off-duty incident in June 2017.

The identity of the charged person is not being released in order to protect the identity of the alleged victim or victims.

Police say the officer is a 22-year member with the force and is scheduled to appear in court in May.

He has been suspended from duty with pay.

But the vagueness of this press release is raising some question marks.

"I do find it odd that they are not stating at least a general location for the Staff Sgt." says former OPP Commissioner, Chris Lewis.

He says had he been in charge when this came across his desk, he would have liked to see a very good reason why so much information is being left out.

"What this tells me is that it's a familial thing in some way, either a family member or a co-worker." says Lewis.

That being said you can give some information, like a region, without giving away exactly where this happened.

"It's going to come out at some point, and in small-town Ontario, generally the town will know very quickly".
