RCMP say Const. Eric Pomerleau was charged this week with common assault related to allegations stemming from August 2012.
They have not released details of the allegations.
Charges of assault with a weapon, assaulting causing bodily harm and common assault were laid last month after a civilian alleged he was pepper sprayed while in police custody in December 2012.
Pomerleau is scheduled to appear in Red Deer provincial court next month.
He’s on administrative duties at another Alberta RCMP detachment.
