An audience member at the Metropolitan Opera threw a white powdery substance into the orchestra pit on Saturday
during an intermission of the afternoon performance of Rossini’s Guillaume Tell, officials said, prompting the company to cancel the rest of the show
and that night’s performance of L’Italiana in Algeri while the police
investigated.
No one was injured during the episode, the Met said, which occurred during the second intermission of the opera. “As a safety precaution, the Met canceled the remainder
of the performance to err on the side of appropriate caution,” Sam
Neuman, a Met spokesman, said.
