Kevin Lenin Saldana, 17, is charged with improper photography/visual recording.
Saldana was charged after he threatened to post topless pictures of his 15-year-old ex-girlfriend on the Internet, according to court documents.
The girl's mother says in April, she began receiving phone calls and text messages from Saldana, according to court documents. During one conversation, Saldana told his ex-girlfriend's mother that if she didn't allow him to talk to her, he would post nude pictures the girl had sent him while they were dating.
Saldana then sent the girl's mother a sample of the pictures he had of her daughter.
Saldana's bond has been set at $2,000. He has not yet been arrested.
