Heart-pounding footage released Tuesday shows the moment a Pennsylvania cop asks accused CEO assassin Luigi Mangione to pull down his face mask at a McDonald’s, revealing him as the wanted suspect.

The stunning bodycam video captures Altoona Police Officer Joseph Detwiler approaching the Ivy League grad at a corner table inside the local fast-food joint on Dec. 9, 2024, and asking the 27-year-old accused murderer to reveal his full face.

Mangione — who was wanted in New York City at the time for allegedly gunning down a health care executive on a Manhattan sidewalk five days earlier — quickly complies.

But he then lies about his name when asked for it, claiming he is “Mark Rosario,” according to the footage, which was recorded on the bodycam from another cop, Tyler Frye, and released as part of a Manhattan proceeding in the sensational case.

“Someone called, they thought you were suspicious,” Detwiler tells Mangione — who replies, “Oh, I’m sorry, um.”

Customers in the McDonald’s at the time have said they recognized Mangione from his distinctive bushy eyebrows — prominently featured in footage released of the slay suspect by Manhattan authorities — before alerting police.

Detwiler then tells Mangione that the caller “thought you looked like someone’’ as he asks the suspect for ID during the increasingly tense encounter,’’ the footage shows.

The clip shows Mangione hand over a New Jersey ID with his face on it, but under the fake name.

The officer hands the ID card to Frye, who relays the information on it over the radio back to their department, the video shows.

The release of the footage came on the fifth day of a pretrial hearing to determine if evidence collected by the Altoona police can be shown at Mangione’s murder trial in Manhattan.

Tuesday also was the one-year anniversary of Mangione’s arrest.

Mangione is accused of gunning down UnitedHealthcare CEO Brian Thompson on a Manhattan street, sparking a furious five-day manhunt for him last year that stretched hundreds of miles.

Mangione, a former prep-school valedictorian, University of Pennsylvania graduate and scion of a wealthy Maryland family, has pleaded not guilty to all charges, including at the state and federal level.

Altoona authorities’ role in the capture of Mangione has come to the forefront over the past two weeks because officers collected troves of pivotal evidence in the case, including the alleged murder weapon, a silencer, a loaded magazine and a so-called manifesto found in his backpack.

Mangione’s legal team wants the items tossed, claiming police needed a warrant at the time of the search while the Manhattan District Attorney’s Office said officers’ conduct was allowed.

Bodycam footage of the cops’ encounter with Mangione was previously viewed in Manhattan court last week before it was released to the public Tuesday.

The footage shown in court shows police grill Mangione at the McDonald’s, including over whether he had been to New York recently and why he lied about his real name.

“You’re under official police investigation,” a cop can be heard telling Mangione as he sits in a chair, staring at the floor. “If you give us false name again, you will be arrested for false identification.”

Another officer, 19-year Altoona department veteran Christy Wasser, testified Monday she also reached the McDonald’s and opened Mangione’s backpack to ensure he didn’t have a bomb inside, though she later admitted to the defense that cops did not clear the restaurant.
