A former U.S. Marine who accused the government of lying about 9/11 and spoke of "The Revolution" on Facebook was detained on Thursday night, reports Renee Nal of Gather.

According to Brandon Raub's mother, authorities from the FBI, Secret Service and Chesterfield County PD came to their door, questioned Raub about his Facebook posts – which are critical of the official story regarding 9/11 and refer to "starting a revolution" – then handcuffed him and placed him in a Chesterfield PD squad car before taking him to John Randolph Psychiatric Hospital in Hopewell, Va.

Raub's mother said he returned about a year ago after serving in Afghanistan (after serving in Iraq) and did not suffer from PTSD.

The Chesterfield PD told us that the situation "was an FBI matter and we were just there to assist them" so it could not provide us with an official reason why Raub was detained.

Raub's mother said that an FBI agent told her Raub was "arrested by the Chesterfield police department" because he "assaulted an officer and resisted arrest," then asked her if Raub "was having any issues relating to people" and told her that "the threats he was making were terrorist in nature."

When asked the Chesterfield PD said Raub has not been charged with resisting arrest and assaulting an officer.

The FBI has told us their agents had "nothing to do" with his detainment and placement in a psychiatric ward.

The Secret Service had no comment.

Here is the video of the arrest:

And this:

There has been an overwhelming amount of evil enacted and planned against you, your children, and your countrymen. It is great in scope. Your government evil. It is as simple as that. And the calvary is coming."

Raub's mother said Raub was told that he will see a judge on Monday but has not been told what he has been charged with and has not been read his rights.
