Columbia, SC (WLTX) - A home security system caught an armed robbery on camera Tuesday in Swansea.

It happened at a home on Sharon Church Road.

In the video, two men can be seen coming out of the woods and entering a shed on the property. The men were wearing dark clothing.

About two minutes after the suspects went into the shed, a woman came outside the shoo a dog away. One of the suspects then ran back into the woods, but the other confronted the woman.

Part of what happened next is obscured by a pool and pool deck that blocks some of the view of the surveillance camera, but detectives believe he pointed a gun at the woman.

The two then got into a fight, and she tried to fend him off, but the man ripped off a gold necklace. The suspect then ran into the woods.

Officers say the victim was roughed up a bit, but is otherwise fine.

Anyone who may have information in the case is urged to call Crimestoppers at 1-888-CRIME-SC.
