HOUSTON -

A teen is charged with improper photography after Houston police say he texted his ex-girlfriend's mother a topless picture of her daughter.

According to court documents, 17-year-old Kevin Saldana threatened to post the picture on the internet if he wasn't allowed to talk to the 15-year-old girl. He then sent a sample picture to the girl's mother.

Saldana told the woman her daughter sent him the picture while they were dating this past April. Charges were filed against Saldana last week.
