A man accused of threatening to blow up a building in Manhattan was arrested by the NYPD in Las Vegas after he barricaded himself in his home for hours, authorities say.

Joseph Amico, who's been arrested 35 times before, is accused of making terroristic threats against a Manhattan attorney who filed a racial discrimination lawsuit against Fox News.

Prosecutors say Amico became enraged and repeatedly called the attorney's office, threatening both him and the Manhattan building he worked in.

The NYPD's Major Case Squad flew out to Amico's hometown of Las Vegas, where he barricaded himself for hours before surrendering to police.

Appearing in court in Manhattan Friday, Amico pleaded not guilty to three counts of making a terroristic threat and four counts of third-degree aggravated harassment as a hate crime. His attorney says his client is being "singled out."

"I don't think anything he did rises to the level of criminal culpability, and I hope this matter is resolved in no time," attorney Todd Spodek said.

Amico is due back in court Monday, when his attorney will make an application for bail.

The attorney who was allegedly threatened by Amico declined to speak to News 4.
