A missionary who works at Sanford based New Tribes Mission has been arrested on charges of sexually abusing children.

Warren Kennell has worked as a missionary for the New Tribes Mission in Brazil for several years and that's where police say the crimes were allegedly committed and some of them actually filmed by Kennell.

Kennell is being held at the Seminole County Jail.

Federal authorities first apprehended Kennell at Orlando international Airport Friday as he was returning from Brazil.

They had received a tip that Kennell had posted child pornography on a website.

Upon interviewing him he told them he had molested four children while working in Brazil all he believed to be around 12-years-old.

Investigators also found images of some of those acts being committed.

The New Tribes Mission has not responded to News 13’s request for an interview. They say they have put Kennell on administrative leave while they gather all the facts saying in a statement they are "heartsick at the thought that children have been victimized."

They go on to say they are trying to confirm whether there is a connection between New Tribes Mission and Kennell's actions.
