Police say two tow truck drivers have been robbed at gunpoint this week on the north side of Indianapolis, likely by the same pair of men. In both incidents, the drivers were contacted to see if they wanted to buy scrap cars. The first incident occurred Tuesday in an alley near the 900 block of West 32nd Street. The second occurred Wednesday in an alley near Ethel Avenue. In both cases, the robbers got away with cash and items including a mobile phone.
