ARLINGTON, Va. (CBSDC) — A pair of would-be armed robbers were scared off by their own exploding firework in Arlington, Va.

Surveillance video shows a masked man entering a 7-Eleven in the 1100 block of George Mason Drive around 3:25 a.m. Aug. 19. As he pointed a handgun at the clerk, a second suspect approached from behind and appeared to throw a lit firework into the store.

When it exploded, both suspects became startled and immediately fled without any money.

The first suspect, who pulled the gun on the cashier, is a white male, roughly 5 feet 8 inches tall with a medium build and black hair. He was wearing a grey hooded sweatshirt, black shorts and had a black bandana covering his face.

The second suspect, who tossed the firework, is roughly 5 feet 7 inches tall with an average build, police say. He was wearing a white v-neck T-shirt and dark shorts at the time.
