A Rotherham man was sentenced to eight months in jail after exposing himself and carrying out a sexual act in front of three teenage schoolgirls.
Mark Antony Dexter, aged 42, pleaded guilty to two counts of exposure at Middle Lane South and Wickersley Road.
He was arrested in October after the mother of one of the girls realised he matched her daughter’s description.
Police Constable Adam Broughton said: “Dexter’s actions were disgusting. I am pleased this matter reached a swift conclusion for the girls who witnessed his despicable behaviour.”
