A large construction crane collapsed onto a street in Manhattan’s densely-populated TriBeCa neighborhood on Friday morning. According to the New York City Fire Department, one death and fifteen injuries have been reported so far. Several vehicles parked on Worth Street, onto which the crane fell, were crushed by the structure.

Authorities are currently investigating unconfirmed reports of a natural gas leak caused by the crane’s collapse. The crane, whose marking identified it as a “Bay Crane” model, was erected in the neighborhood in late January to install air conditioning equipment.

According to outlets reporting from the scene of the crash, the crane appears to have been stationed at or near 40 Worth Street, a 20-story pre-war commercial office building situated between West Broadway and Church Street. Authorities told The New York Times that the initial call came from 57 Worth Street, a smaller building on the corner of Worth and Church. The Metropolitan Transit Authority has rerouted trains to bypass nearby subway stations. The area is currently being secured by at least 100 F.D.N.Y. personnel.

It is not immediately clear what caused the crane to fall.
