A puppet specialist with the Broadway musical “The Lion King” was arrested at the Minskoff Theater last week after he was found inside the prop room manufacturing a 3-D printed gun, according to court records.

The man, Ilya Vett, has been charged with attempted criminal possession of a firearm, a misdemeanor.

Mr. Vett, 47, was listed as puppet dayworker in the Playbill for “The Lion King,” the long-running Broadway show that features a spectacular array of costumes and puppets that help bring the animal kingdom alive.

The police said that company security officials found the gun — or a part of it — when they entered Mr. Vett’s office on Friday. Disney’s human resources department then informed the police that Mr. Vett might have been printing a firearm, the authorities said.
