OMAHA, Neb. (AP) — Police say they’ve arrested a 54-year-old man suspected of raping several women in Omaha dating back to 2006.

Robert Frazier, of Omaha, is charged with raping four women within a three-mile radius in northeastern Omaha. Frazier was arrested in and charged in April with assaulting a 43-year-old woman on April 1. Police say they believe Frazier also raped the same woman in 2011. Police then collected DNA from Frazier, leading them to charge him with the 2011 rape of a 57-year-old woman and the 2006 rape of a 45-year-old woman.

In May, a judge ruled that Frazier should be evaluated by the Lincoln Regional Center so officials can determine whether he is mentally competent to stand trial.
Frazier is being held without bond.
