Police arrested an elderly man on Monday, three weeks after they say he lured children with candy while masturbating.

The 87-year-old Lloyd Harbor man was sitting in his gray 2011 Subaru at West Neck Beach on the afternoon of Aug. 10, when he allegedly offered candy to nearby children. The Suffolk County Police Department said a woman who was at the beach with the kids went up to the Subaru to intervene and saw that the suspect was not wearing pants and was masturbating.

Detectives from the SCPD’s 2nd Squad investigated the case, and on Monday afternoon arrested Horseshoe Path resident Galip Gulmez. He is charged with public lewdness and with endangering the welfare of a child.

Attorney information for Gulmez was not available Tuesday morning.

According to police, the suspect was scheduled to be arraigned on Tuesday.
