The teacher was placed on leave last August as police launched an investigation into possible possession of child pornography.
Police made the arrest at Urias' home in San Jose. They arrested him for possessing and manufacturing child pornography and he was booked into the Santa Clara County Jail.
Authorities had previously collected evidence from his home in Milpitas, his car, and from a classroom at the school. That includes confiscating some computers. They are also doing an additional search of his home in San Jose.
William Rogers Elementary School issued a statement saying there are no known incidents of sexual abuse by this teacher.
However, there is still an active investigation into the possibility of lewd acts with students according to Milpitas police. They've been working with San Jose police, the Alum Rock Union Elementary School District and the Silicon Valley Internet Crimes Against Children Task Force.
