A man suspected of killing UnitedHealthcare’s chief executive has been held in custody after a brief court appearance in Pennsylvania.

Police arrested Luigi Nicholas Mangione on Monday after a McDonald’s employee in Altoona alerted authorities to a customer, who was found with a gun, mask and writings linking him to the ambush.

The 26 -year-old, who was charged with weapons, forgery and other charges, will be extradited to New York to face charges in connection with Mr Thompson’s death.

The chance sighting at the restaurant led to a dramatic break in the fast-moving investigation.

Officer Tyler Frye, who has only been on the job for about six months, and a fellow officer responded to the McDonald’s where the suspect was spotted.

They asked him to pull his blue medical mask down and “recognised him immediately”.

Officer Frye said: “We didn’t even think twice about it, we knew that was our guy.

“It feels good to get a guy like that off the street, especially starting my career this way, it feels great.”

According to court documents, when one of the officers asked Mangione if he had been to New York recently, he “became quiet and started to shake”.

Mr Thompson, 50, was killed last Wednesday as he walked alone to a hotel, where UnitedHealthcare’s parent company, UnitedHealth Group, was holding its annual investor conference.
