A 32-year-old man pleaded guilty in Masterton District Court yesterday to committing an indecent act in a public place.
Police told how Leon Peter Hamlin drove to Millennium Reserve on Hillcrest St, Masterton on October 15, last year, and partially undressed.
He parked his vehicle opposite the gateway to the reserve and walked in.
Once in the reserve Hamlin took off his trousers, leaving him naked below the waist.
A 17-year-old female was walking past the reserve when she saw Hamlin committing an indecent act.
