A store's security guard was no match for a group of young women, all of whom appeared set on shoplifting from a Union Square store.

Police say that the heist went down at 11:27 a.m. Tuesday, at a store on the 200 block of Post Street, a block between Grant and Stockton Streets that's home to a host of high-end designer boutiques.

According to the San Francisco Police Department, a group of five female suspects that looked to be between 16-22 years of age entered a "retail store" carrying a number of bags.

The suspects then "put property into their bags and attempted to leave without paying," according to the SFPD, including at least one purse and a number of belts.

A 21-year-old male security guard attempted to stop the thieves "but was pushed," police say.

The gang of shoplifters fled in an unknown direction. According to the SFPD, the robbers remain at large, and no arrests have been made in the case.
