The suspicious substance that led to last night's evacuation of the Metropolitan Opera House may have been a man's ashes, police said yesterday.

Saturday afternoon around 4:30 p.m., members of the Met's orchestra noticed a man in a suit who began sprinkling a powdery substance in the orchestra pit during the second intermission of "Guillaume Tell." Shortly afterwards, an announcement was made that there would be a delay , attendee Micaela Baranello told the Times. During the lengthy intermission, security guards began to stand near the pit.

The Met canceled the remainder of the performance before evacuating the building altogether. After the evacuation was announced, some patrons began booing and shouting for their money back. According to the Daily News, a later show—"L'Italiana in Algeri"—was also canceled.

John Miller, the NYPD's Deputy Commissioner for Intelligence and Counterterrorism, told reporters last night that the man had told other members of the audience that he was attending the opera to sprinkle his mentor's ashes during the performance. Miller said the man was violating the health code but did not appear to have any criminal intent.

An NYPD spokesperson told Gothamist yesterday that the man fled the theater after the incident, but police now think he may have just walked off after the tribute.

"I don't think he had any reason to believe what he did was wrong," Miller said.

Police have identified the man but have not charged him with anything. The Post reports the man was Roger Kaiser, a tourist from Dallas.
