The Pennsylvania man was arrested at 4:45 p.m. Friday by U.S. Marshals in Mifflin Township.
A federal warrant was issued in June for the 27-year-old in connection with Facebook posts threatening to shoot President Donald Trump and a district attorney in the Lehigh Valley.
Pennsylvania warrants issued for Christy allege burglary, probation violation and failure to appear for an aggravated assault case.
The search most recently led authorities to Ohio where they found a stolen truck on the side of a highway on Sunday.
Earlier this week, Christy's father made a plea to his son to turn himself in, sending the message from his hometown in Schuylkill County.
"Surrender yourself, son, you proved your point. It's like a dream, a nightmare that don't end," he says.
Craig Christy said he does not believe his son wants to hurt anyone, that he is simply on a quest for justice.
