OKLAHOMA CITY - The Oklahoma County District Attorney has filed charges against a 28-year-old man suspected of demanding explicit pictures from a 17-year-old girl.

Police said David Adam Wheeler obtained the girl's cell phone number from her Facebook page. According to court documents, he then sent her texts demanding she send nude photos of herself, and threatened to send nude photos of himself to her if she didn't comply.

Police said Wheeler also demanded the girl have sex with him. The teen refused his demands and contacted police.

Police arrested Wheeler on an unrelated, outstanding warrant. When officers questioned him, Wheeler said he did not know the victim, but he admitted to contacting her and sending pictures of himself. He also said he'd done the same thing to other females.

Wheeler has been charged with soliciting sexual conduct with a minor, and making obscene, threatening, or harassing communications.
