The FBI has arrested a man accused of making violent threats against freshman Rep. Tulsi Gabbard (D-Hawaii) -- threats that included her decapitation.

Aniruddha Sherbow was arrested Wednesday in Tijuana, Mexico, and turned over to FBI agents in San Diego, according to the FBI. He is set to appear in court Thursday before being returned to Washington.

The FBI says Sherbow sent the threats to them earlier this month.

“I, Aniruddha Sherbow, with the Divine as my witness, do hereby solemnly vow to find Tulsi Gabbard, wheresoever she may be, and to sever her head from her body,” he wrote, according to local reports.

Sherbow is charged with transmission of threats in interstate commerce.

It's not Gabbard's first run-in with Sherbow. In 2011, a judge issued a three-year restraining order against him after a series of threatening and abusive phone calls and text messages to Gabbard, who was then a city councilwoman.

Updated at 4:09 p.m.: Sherbow's first court appearance has been pushed back to Friday, according to the FBI.
