T.J. Miller Busted for Giving Feds False Info About Amtrak Bomb Threat

EXCLUSIVE

8:50 AM PT -- Miller was arrested by FBI agents over an Amtrak bomb threat he reported back in March. 

According to the FBI docs, Miller called 911 on March 18 while he was riding an Amtrak train from D.C. to NYC ... and reported a woman with brown hair and a scarf "has a bomb in her bag." An Amtrak police officer called back Miller who added ... the woman kept checking the bag and seemed to want to get off the train and leave it behind.

The officer asked Miller if he suffered from mental illness ... which he denied, and said, "This is the first time I've ever made a call like this before. I am worried for everyone on that train. Someone has to check that lady out."

As it turns out ... Miller gave cops the wrong train number, and as a result a different train was stopped in Connecticut, evacuated and searched ... causing massive Amtrak delays. Meanwhile, Miller was on his train to NY.

According to docs, Miller was removed from the train in NYC because he was intoxicated. The train attendant said Miller had consumed 2 glasses of wine and 2 double Scotch and sodas. The attendant also reported Miller had "exchanged profanity" with a woman in the First Class car -- and he did not back up Miller's account of the woman's suspicious behavior.

The woman told police Miller was being loud and belligerent on the train, and had made a comment about her hair. She admits they had an argument.
