A robbery in Prescott Valley Monday has led to an arrest. Police say a man was in his parked car at the David Fast Stop on North Robert Road at around 8:25 p.m. when two males, one adult and a teenager, approached the vehicle. The adult pulled a knife, placed it to the victim’s neck and demanded all his money. The victim was able to protect himself in a way that caused the suspects to flee the scene. Officers caught up with the suspects, 19-year-old Francisco Castro and the 14-year-old and placed them under arrest. Castro was booked into the Yavapai County Detention Center for robbery, marijuana possession and drug paraphernalia. The teenager was booked into the YCSO Juvenile Detention Center for the same charges.
