A man set himself on fire in a park across from the Manhattan courthouse where former President Donald Trump’s hush money trial is taking place, officials said Friday.

Maxwell Azzarello walked into Collect Pond Park around 1:30 p.m. Friday before taking out what police believe was an alcohol-based cleaner and pouring it on himself, NYPD officials said at a news briefing.

Azzarello then set himself on fire, fell onto a police barrier and fell to the ground, where court and police officers, and members of the public, rushed to put the blaze out using clothes and an extinguisher, police said.

The FDNY responded to the scene shortly after and took Mazzarello to the burn unit at New York-Presbyterian/Weill Cornell Medical Center, where he was listed in critical condition, according to police.

Officials said it all happened quickly.

“Nobody knew that this guy was about to light himself on fire, so two minutes is a pretty good response time,” Tarik Sheppard, the NYPD’s deputy commissioner of public information, said at the briefing.

Police described Mazzarello as a man in his 30s from St. Augustine, Florida. They said he arrived in the city between April 13 and Friday, and that his family was unaware he was in New York.

NYPD officials said Mazzarello was throwing pamphlets into the air throughout the park before he grabbed the cleaner he used as an accelerant.

“The pamphlets seem to be propaganda-based, almost like a conspiracy theory type of pamphlet,” NYPD Chief of Detectives Joseph Kenny said. “Some information in regards to Ponzi schemes, and the fact that some of our local educational institutions are a front for the mob.”

Multiple media organizations, including Spectrum News NY1, received a communication that is believed to have come from Mazzarello containing a series of writings on the internet that appear to have come from him.

Police said they will scrub Mazzarello’s social media accounts. They said he has no criminal history in New York.

FDNY Commissioner Laura Kavanagh said three NYPD officers and one court officer sustained minor injuries as a result of the fire, but noted that they were all in stable condition.

The Office of Court Administration said three court officers suffered smoke inhalation.

NYPD Chief of Department Jeffrey Maddrey said Mazzarello did not breach security protocols before the incident, as the park was open to the public at the time.

A full jury of 12 people and six alternates had been seated in Trump’s hush money case just minutes earlier, drawing the first criminal trial of a former U.S. president a step closer to opening statements.
