(DNAINFO)  Noah Horowitz | December 14, 2015 — Arrests for public lewdness more than doubled in the 13th Precinct.

The number of people arrested for public lewdness has shot up nearly three-fold in Gramercy — mostly due to people exposing themselves on the subway and at least three instances of couples having sex in public within the past two months, according to the NYPD.

Between Jan. 1 and Nov. 17, there were 20 arrests for public lewdness at the 13th Precinct — which covers Union Square, Flatiron, Stuyvesant Town, Gramercy and Kips Bay — compared to just eight arrests for those crimes during the same time period last year, NYPD data shows.
