Columbia Police are asking for the public's help in tracking down two armed robbers who have targeted four businesses in the last two weeks.

In three of the cases the robbers got away with cash, in the fourth, the robbers ran away after firing a gun but before getting any money.

“Any time a person uses a weapon it's dangerous, because you don't know what their intentions are,” Columbia Police Department Spokesperson Latisha Stroer said.

The firing of the gun happened during a late-evening armed robbery attempt at the Taco Bell on Smiley Lane on July 25th. An employee was hit in the leg by a bullet fragment or other debris and was treated at the scene, police said.

Police have no named suspects and are working off of very vague descriptions of the robbers: two black males in their late teens to early twenties, both around 6' tall and wearing dark clothing.

In all four locations, surveillance cameras failed to capture any images of the crime duo.

A fifth armed robbery, at the Martinsburg Bank on South Providence on July 27th, does not appear to be connected to the other robberies, according to police.

Police said the men should be considered armed and dangerous and ask anyone with information to call them at (573) 874-7460.
