A man is now behind bars after a sting to catch online sexual predators.

Authorities say 26-year-old Ryan Michael Sims drove 23 hours from Missouri to Walker to meet with someone he thought was a 15-year-old girl he met online.

Police say Sims wasn't aware that the young girl was actually part of a sexual predator task force.

When he arrived over the weekend, he was arrested.

Authorities believe this should be a wakeup call to parents.
