A children’s hockey referee was responsible for a string of subway gropings that included teenage girls and, in an odd twist, two twin sisters who were attacked five years apart from each other.  Kenneth Jacobson, 44, is charged in five separate molestations on the No. 1 train, the earliest dating back to 2011.  Jacobson, a freelance hockey referee, works at the Chelsea Piers with children, prosecutors said at his arraignment Tuesday night. He would either put his hands under his victims’ skirts, or on their genitals on top of their clothing, prosecutors said.  Two victims were 13 years old, while a third was 16, prosecutors said.  Twin sisters groped by same perv in subway five years apart  Four separate witnesses identified him in a lineup, prosecutors said.  He was arrested around 5:45 p.m. Monday, after cops shared a photo of Jacobson over the weekend hoping to identify the perv.  In one case, an 18-year-old woman told police he groped her on Sept. 9 near the 42nd Street station, cops said. Her twin sister saw his photo, and realized he had groped her by the 110th St. station when she was 13 years old — sometime between Sept. 29, 2011 to June 30, 2012, sources said.  In another instance, he cozied up to an 18-year-old woman on the train near Times Square on Sept. 21 and touched her thigh, authorities said.  His lawyer, Howard Weiswasser, denied the allegations.  “The identification was based on a picture of him holding the pole in the subway, not touching victims. He's a good kid. He has no record. He works hard and denies all the charges,” Weiswasser said.  Jacobson has prior arrests in Manhattan dating back to 2000 and 2006, but those cases have since been sealed, cops said.  Jacobson, who could face two years behind bars, was ordered jailed on $20,000 bail.  His father, who was trying to raise the money for his release Tuesday night, declined comment.
