Investigators are still searching for four suspects after an armed robbery in Saskatoon on Monday night.

Police say three men and a woman entered a convenience store on 29th Street West just after 7:15 p.m.

One man was armed with a handgun and ordered the lone employee to the floor, police said in a media release.

The suspects stole cash from the till and cigarettes.

Police say the four were last seen on foot eastbound on 29th Street. A police dog was unable to track them down.

All four suspects are described as aboriginal and were wearing bandanas over their faces. Two were wearing Toronto Raptors ball caps.
