NEW YORK (CBSNewYork) — A registered sex offender wanted in connection with a series of subway flashings is in custody.

Kenneth Hoyt, who is suspected of exposing himself to at least three different women on the R train since August, has turned himself in.

Police say the suspect was not wearing pants or underwear and just lifted up his shirt and flashed the women on the train.

Hoyt has been a registered sex offender since 1987 when he was convicted for having sex with a 13-year-old girl.

He was arrested six times in 2006 for lewdness-related crimes.
