Police Seize Two Guns Licensed to Stewart J. Rahr, New York Billionaire The police have confiscated two guns belonging to a New York billionaire and are weighing whether to revoke his handgun license after officers responded to an incident this month at Trump Tower, according to a police official and two people familiar with the matter. The billionaire, Stewart J. Rahr, 66, a philanthropist who calls himself the "No. 1 king of all fun," declined to comment on Wednesday. Details of the incident at Trump Tower were not immediately available. But Benjamin Brafman, a lawyer retained by Mr. Rahr, said in a statement: "There was a minor incident that the police are reviewing, as is standard practice. Based on my understanding of the facts, I am very confident that the matter will be closed without any formal proceedings whatsoever as Mr. Rahr did absolutely nothing wrong. The police were summoned to Trump Tower in Midtown Manhattan, where Mr. Rahr has an office, on Nov. 1 after a heated exchange involving Mr. Rahr and an elevator operator, said one of the two people familiar with the matter. Both declined to be identified because they were not authorized to discuss the incident publicly. Paul J. Browne, the Police Department's chief spokesman, said the responding officers seized a gun from Mr. Rahr and took him to a hospital for a psychological evaluation. A person close to Mr. Rahr, who spoke anonymously for fear of alienating him, identified the hospital as St. Luke's-Roosevelt Hospital Center and said he was released in less than an hour. Mr. Browne said officers later confiscated a second gun at Mr. Rahr's residence. Both weapons were registered to Mr. Rahr, and his license was suspended while the investigation continued, Mr. Browne said. The encounter came a few days after Mr. Rahr was involved in an exchange at the restaurant Nobu 57 that led it to ban him from all restaurants owned by Nobu Group, according to a person familiar with the encounter. That incident was first reported by The New York Post. As part of the inquiry into Mr. Rahr's handgun license, an investigator questioned Nobu staff members on Monday, the person said. Mr. Rahr, who according to Forbes has a net worth of $1.6 billion, turned a pharmaceutical distributorship founded by his father in Queens into a billion-dollar enterprise. He sold the company in 2010. Mr. Brafman said his client had been licensed to carry a weapon for more than 40 years "for his personal protection."
