(AP) — A 28-year-old Lincoln man has been sentenced to jail for groping or slapping the backsides of women jogging on city trails.

Christopher Jackson was sentenced on Monday. Online court records say Jackson had pleaded no contest to three counts of sexual assault and one count of misdemeanor assault.

Lincoln police say women had reported separate incidents in September. They said their attacker would ride up on a bicycle from behind them and would reach out to grab or slap their buttocks.
