Police say a 20-year-old woman was leaving her job shortly early Thursday morning at a hotel in Red Deer, Alta., when a man came to her driver's side door and brandished a knife.
The male forced the female to get in the passenger seat and he drove to a bank where he took her to the ATM and forced her to withdraw money from her account.
RCMP say he then took her to a rural location near Penhold where he sexually assaulted her before driving her back to Red Deer and dropping her off at a convenience store and leaving with her vehicle.
Mounties say Justin Chase Mueller is facing several charges.
Police say they believe Mueller has left Red Deer and may be heading to Edmonton, and warn he is armed and possibly dangerous and to contact police if seen.
