The Regina Police Service is making residents aware of an alleged sexual assault that happened on Sunday.
Police say there is a potential risk to public safety and would also like help solving the case.
The alleged assault took place outside a building in the area of the 2900 block of 14th Avenue sometime between 3:30 and 4 a.m.
Police say the woman, who was allegedly assaulted, made her way into the building and then to hospital following the event.
Officers were called to the hospital at about 8:30 a.m. Police canvassed the neighbourhood for evidence.
