(Las Vegas, NV)  –  A Henderson man is accused of posing as a cop and sexually assaulting an 18-year-old woman.  Metro Police say 67-year-old Donald Caterino gave the woman a ride Monday night near Boulder Highway and Lamb, then flashed a badge and told her she was under arrest.  Police say the victim was then handcuffed, taken to the suspect’s home and assaulted, then dropped off at a Boulder Strip casino.  Caterino claimed the woman was a prostitute who retaliated because he refused to pay her.
