A Wichita Falls man has been charged with making threats to blow up a Federal Court House.
Christopher Stephens appeared in federal court Tuesday in Wichita Falls.
Authorities said the 34-year-old called the US Courthouse in Dallas several times, threatening to blow it up.
Stephens made the same threats in two different letters at the time he was accused of making the threats.
He resided at the North Texas State Hospital in the Falls.

The US Attorney's Office has 30 days to present the matter to a grand jury for indictment.
Stephens is charged with one count of using the mail to willfully make a treat to unlawfully damage or destroy a federal courthouse by means of explosion.
Stephens faces up to ten years in Federal Prison and a $250,000 fine.
