Jack Roach, 19, was taken into custody at 11 a.m. for promoting the sexual performance of a child. AOL alerted authorities in May that an email account originating in Farmingdale was used to send child pornography of a female engaged in sex acts, police said.

Roach is charged with two counts of promoting the sexual performance of a child. He will be arraigned Saturday in First District Court in Hempstead.
