(CNN) A recently installed wind turbine came crashing down in a New York City neighborhood, causing a chain reaction on Monday.

As the turbine in the Bronx partially collapsed, it smashed into an adjacent three-sided illuminated billboard, causing that also to break apart and come tumbling down to the street and cars below.

Pictures from the scene shot by Tori McCauseland with The Co-op City Times show a massive pole lying across a mangled car.

"Thankfully we can report that there are no injuries, and everyone is safe and sound," New York Mayor Bill de Blasio told CNN affiliate WABC. "An investigation into how this incident happened is underway."

The wind turbine, which is more than 150 feet tall, was installed in mid-December but had not yet been activated, according to WABC. Debris was strewn across the shopping center below that houses a gas station, pharmacy, paint store and other businesses. All the stores were evacuated, according to the New York City Department of Buildings (DOB).
