Ice broke through a glass atrium at the Sony Building in New York City injuring 10 people, officials said.
A spokesman for the New York City Fire Department said ice and glass fell into the lobby area of the Madison Avenue building on Saturday night.
The spokesman said no one was seriously hurt, and that the injured were taken to area hospitals. A spokeswoman at Roosevelt Hospital in Manhattan says four of the injured were taken there with minor injuries.
No other information about the incident was immediately available.
The New York Post and celebrity Web site TMZ reported Sunday that "Jersey Shore" cast member Nicole "Snooki" Polizzi was among those attending a party in the building. The Web sites reported Polizzi said on Twitter after the incident: "Omg roof just collapsed!"
A call and e-mail to Polizzi's agent was not immediately returned.
