The footage, which was taken around 4 a.m. Monday, shows two people lighting and throwing the firework at a 66-year-old homeless man who was sleeping on the sidewalk. The firework then explodes.
The NYPD is investigating the attack, saying the man is in stable condition.
It is just one of more than 13,000 complaints involving illegal fireworks received by the city this month -- compared to just 32 between June 1 and June 22 in 2019 -- leaving many fed up and sparking a drive-by protest with horns honking outside Gracie Mansion overnight.
In response, Mayor Bill de Blasio announced the creation of a task force to crack down on illegal fireworks sales.

"It's more than we've ever seen it," he said. "Illegal fireworks are both dangerous and a public nuisance. We're cracking down on this activity at the source to ensure the safety of all New Yorkers and the ability of our neighbors to get some sleep."
The task force will target suppliers, distributors and possessors of large quantities of illegal fireworks by conducting investigations and sting operations within and outside of New York City to disrupt supply chains. The FDNY will also launch a public safety campaign, including public service announcements and social media, to illustrate the dangers of illegal fireworks.
The task force will consist of 10 officers from NYPD Intelligence Bureau, 12 FDNY Fire Marshals and 20 members of the Sheriff's Bureau of Criminal Investigation.
"For any number of reasons, the use of illegal firework has skyrocketed this year and that has damaged the quality of life in our neighborhoods," Police Commissioner Dermot Shea said. "The NYPD will continue to work closely with our city partners to address this dangerous issue."
