Sergey Macheret, 65, was arrested Wednesday after the Lafayette Police Department's weeks-long investigation into several complaints of a "suspicious male approaching women," according to Indianapolis news station Fox 59. The department's investigation, which began in December, led them to Macheret, per the outlet.

Macheret will be charged with making an unlawful proposition, dealing methamphetamine, and possession of methamphetamine, per Fox 59. It's not clear if he has retained a lawyer who can comment on his behalf. The Lafayette Police Department did not immediately respond to PEOPLE's request for comment.
