The man accused of attacking three NYPD officers with a machete in Times Square on New Year's Eve was charged with attempted murder by federal prosecutors Tuesday.

The Manhattan district attorney also arraigned Trevor Bickford, a 19-year-old from Wells, Maine, on terrorism charges last week.

Federal prosecutors charged Bickford with four counts of attempted murder of officers and employees of the U.S. government and persons assisting them. If convicted on each count, he faces up to 80 years in prison, officials said.

In a release, prosecutors with the U.S. Attorney's Office for the Southern District of New York outlined Bickford's alleged plot to kill the police officers as part of his "jihad" against the U.S. government, which he viewed as anti-Muslim.

"On this past New Year's Eve, revelers flocked to Times Square to ring in the New Year with friends and family. But Trevor Bickford allegedly targeted the iconic yearly celebration to carry out a brazen act of violence and hatred in the name of jihad," U.S. Attorney Damian Williams said in a statement. "Bickford's alleged attack in one of the most visited destinations in the world on its busiest night of the year ironically only served to spotlight the coordination, resolve, and dedication of American law enforcement to guard the wellbeing of the public."

Bickford's attorney did not immediately return a request for comment.

Bickford is accused of approaching three officers at a security checkpoint near 52nd Street and Eighth Avenue just after 10 p.m. on New Year's Eve. Prosecutors said he said "Allahu Akbar" - Arabic for "God is great" - and stabbed and struck the officers in the head with a one-foot long blade. All three officers would later be hospitalized.

As the attack unfolded, Bickford attempted to take a firearm from one of the officers, officials said. Then, another officer shot Bickford in the shoulder and the NYPD took him into custody.

"We are deeply grateful for the bravery of the officers who were injured in this horrible attack and who put their lives on the line every day to serve their communities," U.S. Attorney General Merrick Garland said in a statement.

Bickford allegedly became radicalized during the summer in 2022, reading radical Islamic literature that promoted the Taliban and the teachings of Abu Muhammed al-Maqdisi, who prosecutors described as "a spiritual mentor” of al-Qaida.

By November, he planned to travel to Afghanistan to work with the Taliban and wage war against "officials of governments that he believes are anti-Muslim, including the U.S. Government," according to the release. Investigators said Bickford told a family member he hoped to be a suicide bomber.

Ultimately, prosecutors allege, Bickford decided to attack targets in the United States and settled on Times Square on New Year's Eve.

In a police interview while he was being treated at a hospital after the attack, Bickford said he planned on dying during the attack "in an effort to achieve martyrdom," according to the release.

Last week, Manhattan prosecutors charged Bickford with three counts of first-degree attempted murder in furtherance of an act of terrorism, one count of aggravated assault on a police officer as a crime of terrorism, two counts of first-degree attempted assault as a crime of terrorism and two counts of attempted aggravated assault upon a police officer as a crime of terrorism.
