Luigi Mangione, suspected of assassinating UnitedHealthcare CEO Brian Thompson, lashed out at court officials at an extradition hearing in Pennsylvania on Tuesday, saying the charges were an “insult to the intelligence of the American people.”

The 26-year-old appeared in a Blair County courtroom for an extradition proceeding at 1:30 p.m., a day after his arrest at a McDonald’s in the city of Altoona when a worker recognized him from widely-circulated surveillance video images.

After arriving at court in an orange jumpsuit, he was seen struggling with court security officers and yelling. Mangione was denied bail at the hearing, according to The Associated Press. His local defense lawyer, Thomas Dickey, said he wanted a hearing into his extradition, for which prosecutors have a month to seek a governor’s warrant.

In a sealed complaint, Manhattan prosecutors on Monday accused Mangione of second-degree murder, three weapons possession offenses, and criminal possession of a forged instrument, stemming from the CEO’s early morning murder on Dec. 4 outside the Hilton Hotel on Sixth Ave. near W. 53rd St.

“The defendant is the person shooting and killing Brian Thompson in the above-described surveillance footage,” NYPD Det. Yousef Demes wrote in a Manhattan Criminal Court filing made public earlier Tuesday designated as a felony arrest warrant, describing the widely-watched footage of the shooting.

The 26-year-old was held without bail in Pennsylvania late Monday after being brought up on charges alleging he illegally carried a weapon, forgery, and related offenses. Mangione was arrested after being spotted more than 200 miles from the scene.

Surveillance video captured Mangione, 26, leaving the HI New York City Hostel on Amsterdam Ave. near W. 104th St. at 5:34 a.m. on Dec. 4 wearing the same clothing as the shooter, according to the New York court filing.

He was captured checking into the hostel on Nov. 24, at about 11:20 p.m., with the fake driver’s license for one Mark Rosario that he presented to the Pennsylvania cops who arrested him at the McDonald’s just before 10 a.m. Monday, the filing alleges.

Altoona, Pa., cops recovered a semi-automatic pistol with what appears to be a 3D printed loaded receiver with a metal slide and silencer and written admissions about the crime, the filing details.

A warrant for Mangione’s arrest signed by Manhattan Criminal Court Judge Michael Ryan was separately filed publicly Tuesday. It included a Towson, Md., address for Mangione and described him as 5-foot-10 and weighing 140 pounds.

The Manhattan DA is waiting to see if Mangione waives his extradition to New York to determine the next steps, a spokesperson said. He’s being held at a state correctional facility in Huntingdon, Pa.

The Daily News could not immediately reach Dickey for comment.
