SAN ANTONIO -- A man is accused of trying to lure a teen into sex through Facebook messages.

The San Antonio Police Department said 22-year-old Darion Williams was arrested over the weekend on several charges, including online solicitation of a minor.

According to an arrest warrant, Williams started Facebook messaging a 14-year-old girl who lived in his apartment complex in early September.

The warrant states the messages were sexually explicit.

Investigators said Williams admitted to knowing the girl's age. Her mother reportedly saw the messages and contacted authorities to ensure they would no longer be in contact.

Court records show Williams was convicted of indecency with a child by exposure in 2013.
