Indianapolis police said an officer interrupted a newlywed couple having apparent sexual  intercourse in the parking lot of a motel.  An officer patrolling a Westside area spotted activity in a car parked at the edge of a motel lot.  "I observed two people in the car," Officer Brady Ballwrote in his report of the incident. "I observed a woman straddling a man. She was on top of the man and moving up and down on him with both people in the driver's seat."  The officer said he turned his spotlight on the couple and saw they were both exposed below the waist when they quickly changed positions.  The report said the man, 20, and woman, 28, said they were newlyweds having a spontaneous sexual romp in the parking lot.
