The FBI has arrested a man accused of threatening to decapitate Rep. Tulsi Gabbard (D-Hawaii), federal officials announced on Thursday.
The FBI took custody of Aniruddha Sherbow on Wednesday after Mexican police in Tijuana arrested him on an outstanding federal warrant.
Sherbow also allegedly sent at least one of the emails to the FBI, at which time officials began investigating the matter along with U.S. Capitol Police.
In 2011, while Gabbard sat on the Honolulu City Council, a local court granted her a 3-year restraining order against Sherbow after the lawmaker reported receiving nearly three-dozen aggressive and harassing phone calls and text messages from him.
Sherbow is scheduled to have his initial court appearance on Thursday in San Diego, after which he is slated to be flown to Washington, D.C., where he will face an outstanding charge of transmission of threats in interstate commerce.
A spokeswoman for Gabbard declined to comment beyond saying that the lawmaker was "grateful" for the work of the FBI and the U.S. Capitol Police.
