BATON ROUGE - A 21-year-old Mexican national living in Baton Rouge was arrested Monday for allegedly having inappropriate conversations online with a person he believed to be a juvenile. 

Louisiana State Police said a joint investigation with the Baton Rouge FBI and Pointe Coupee Sheriff's deputies ended with the arrest of Javier Mendoza Valiente. 

Troopers said Valiente had sexually explicit conversations with a person whom he believed to be a 15-year-old. 

Valiente was booked into East Baton Rouge Parish Prison for computer-aided solicitation of a minor and indecent behavior with a juvenile.
