A large construction crane collapsed Friday on an apartment building in Manhattan's Upper East Side, killing one person.

According to Reuters, the New York City Fire Department said that the victim was the operator of the crane and he died shortly after 8 a.m. They also said that some other people were rescued but their condition was not known.

The top of the crane smashed into “The Electra” apartment building on East 91st Street, causing damages to the balconies and filling the street below with debris.

The crane was working on a building, just across the street, when the top piece flew right into the apartment building which was about 20 stories high.

This was the second Manhattan crane collapse in two months, reported The New York Times. In March, a tower crane crashed on East 51st Street, killing 7 people and injuring about 10.

The accident happened just after the Buildings Department said that it would no longer be necessary for the workers to be at the construction site when a crane was made taller. They want to create a safer system so that the workers are informed about the proper procedures.

Mayor Michael R. Bloomberg said Friday that the New York City officials have to determine the cause of the accident and to prevent the situation to occur again.
