A person with a gun who police say was trying to get attention was apprehended late Monday morning on UnitedHealthcare’s campus in Minnesota.

No one was hurt at the health insurance company’s headquarters in Minnetonka, and the man, who had parked his vehicle near a loading dock, surrendered after about an hour of negotiations, Minnetonka police spokeswoman Jessica Case said.

The incident happened more than four months after UnitedHealthcare CEO Brian Thompson was shot in New York City in an ambush killing that police said was targeted.

The man arrested Tuesday said he went near UnitedHealthcare and called in only because he thought it would get attention and maybe help him with his past criminal cases, Case said.

The FBI said the man called the agency’s Minneapolis field office around 10:45 a.m. “and issued threats of violence directed at the United Healthcare facility if specific demands were not met.”

“While the investigation is still in its early stages, there is currently no indication that the individual had specific grievances against United Healthcare,” the FBI said in a statement.

City spokesman Andy Wittenborg said the man has a history with Minnetonka police and is known to them. A gun was found in the passenger seat, he said.

Thompson’s slaying on Dec. 4 sparked a nationwide manhunt that ended five days later when Luigi Mangione, 26, was arrested at a McDonald’s in Altoona, Pennsylvania, police said.

Thompson’s slaying near the Hilton New York Midtown spurred a massive amount of online support for Mangione, who has been charged on state and federal counts.

Attorney General Pam Bondi has directed prosecutors to seek the death penalty, which defense lawyers called a “political stunt.”

Hours after the shooting, Thompson’s wife, Paulette Thompson, said her husband had been receiving threats.

“There had been some threats,” she said. “Basically, I don’t know, a lack of coverage? I don’t know details. I just know that he said there were some people that had been threatening him.”

In an unrelated matter, Rep. Greg Murphy, R-N.C., lashed out at UnitedHealthcare on Monday afternoon for aggressively recouping loans it gave out to health care providers affected by a cyberattack last year.

The breach slowed or stopped payments to thousands of front-line medical providers.

The company had helped many of those providers with interest-free loans until the mess could be hashed out. But now UnitedHealthcare is going after borrowers, demanding they “immediately repay” their outstanding balances, according to documents viewed by CNBC.

“Imagine UnitedHealthcare going back on their word, after a payment crisis they were responsible for, with predatory practices on those who actually care for patients,” Murphy, a physician, said in a statement Monday. “They continue to double down on destroying their reputation.”

Representatives of UnitedHealthcare, the nation’s largest private health insurer, could not immediately be reached for comment.
