ROCK HILL — One of two alleged victims in a Rock Hill home invasion ran away after he was apparently tied up and pistol-whipped Monday night, police say.

Police were called to a Maple Street house close to 9 p.m. when a 55-year-old man told them two short, masked men broke into the house, forced him to the floor and tied up his 24-year-old nephew, according to a Rock Hill police report. They pistol-whipped the nephew after ransacking the house and stealing $20, the report states.

When the robbers left, the nephew ran and wasn’t on scene when police arrived. The man’s uncle said the masked men called his nephew “uncle” — a nickname the nephew’s friends often use to refer to him.

Police have still not been able to find the nephew, the report states.
