NYC terror attack: Josh Groban shares personal account, stars express sympathy for victims

WATCH: Josh Groban shares account of NYC terror attack

When a suspected terrorist careened into pedestrians and cyclists on a bike path in New York City Tuesday, killing eight and injuring several more, actor Josh Groban was right nearby.

The Broadway star and Grammy nominee documented the quick response from the local police and other first responders.

"Oh my god I just heard gun shots and ran with my dog," he wrote. "Once I got far enough away I took this video of the quick response from our amazing NYPD and NYFD."

I hope everyone’s ok. Was half a block from me, didn’t see it but heard 8-10 quick rounds fired off. Be safe with your kids out there.

I’m shaking. That’s the corner I was supposed to have my coffee but my dog pulled me into the park half a block away 10 min before shooting. https://t.co/AvQeRv7Jha
