A construction crane toppled onto an office building on Long Island Thursday morning.

It happened on Broadhollow Road in Melville around 9 a.m., with the crane crashing into a building that houses an accounting firm.

Fortunately, none of the 15 employees inside was injured.

A company called “MCN Distributors” out of Islandia was apparently removing two air conditioner/heating units and delivering new ones at the time.

The Occupational Safety and Health Administration (OSHA) is on scene.

It is unclear what caused the crane to tip over.
