Two men who were just trying to sell some stuff online had their pants (and more) stolen Wednesday, even though they met their robbers on a busy San Francisco street.

According to the San Francisco Police Department, the male victims (aged 18 and 23) had arranged "to sell goods through an online ad" to prospective buyers meeting them on the 1700 block of Sloat Boulevard, which is between 34th and 35th Avenues.

When the buyers, two men in their 20s, arrived, one of them "showed [the 18-year-old victim] a gun in his waistband and demanded property." The gun-wielding man then forced the 23-year-old victim to "go to an ATM to take out more cash."

All in all, the two suspects stole the men's cell phones, wallets, credit cards, and cash. They also swiped their shoes and jeans, police say.

The suspects hopped into a nearby vehicle and fled in an unknown direction, police say. As of publication time,the men remain at large and no arrests have been made in the case.
