LINCOLN, Neb. (AP) — A man has been charged with trying to have sex with a girl in exchange for trading cards and a DVD player.

25-year-old Joshua D. Vrana was charged Monday with attempted first-degree sexual assault of a child. He is being held at the Lancaster County jail on $100,000 bond.

Authorities say a Nebraska State Patrol investigator received a tip about an exchange on an online dating site in which a user claimed to have a 25-year-old friend who wanted to have sex with a 16-year-old’s younger sister. After identifying the user as Vrana, investigators contacted the suspect pretending to be the 16-year-old girl.

Authorities say they met July 1 at a public library, where Vrana was arrested.

Vrana has been appointed a public defender.
