Federal authorities have detained a man who they say admitted to driving a car into a disputed Ten Commandments monument outside the Oklahoma Capitol building, smashing it to pieces.

U.S. Secret Service agent David Allison says the man was detained Friday after he showed up at a federal building in Oklahoma City, rambling and making derogatory statements about the president.

Allison says the man admitted to destroying the monument and claimed Satan told him to do it.

The 6-foot-tall monument was erected in 2012 with the blessing of Oklahoma's conservative Legislature. The American Civil Liberties Union of Oklahoma has been suing to have it removed.

Other groups have asked to erect their own statues, including a satanic group that wants to put up a 7-foot-tall statue of Satan.
