Phoenix police are asking for your help in tracking down a woman they say robbed a Circle K convenience store earlier this month.

The suspect (she's that trucker-lookin' lady in the picture), police say, entered the Circle K near 19th and Peoria Avenues in Phoenix on June 6, about 2 a.m.

After entering the place, the suspect -- described by police as a white female about 33-37 years old, 5-foot-5 to 5-foot-6 inches tall, 180 pounds, with brown hair -- approached the clerk, pulled out a three-inch knife and demanded cash.

The clerk handed over the dough and a few packs of cigarettes, and the suspect was out the door on foot -- but not before posing for a surveillance-cam photo shoot.

No vehicle was seen during the robbery.
