PITTSBURGH — Pittsburgh police say they’re looking for a clumsy crook who robbed a convenience store while wearing a Darth Vader mask.

Police spokeswoman Sonya Toler says the suspect had a knife when he entered the CoGo’s store in the city’s South Side about 12:45 a.m. Wednesday.

As the man came around the counter after demanding money, he tripped and fell into a floor fan.

Police say the suspect took some money then ran away.

Despite the mask, police say the clerk described the robber as a slightly-built black man, about 5-foot-5 and 110 pounds.

In addition to the Star Wars villain’s mask, the suspect wore a black hooded sweat shirt and shoes and khaki pants.
