A madman went on a chaotic joyride through Brooklyn Sunday afternoon after allegedly stealing a FedEx truck and crashing into multiple vehicles and a church fence before attempting to hijack an ambulance, according to authorities.

Domanique Bullock allegedly hopped into a parked FedEx truck outside of 606 Carroll Street in Park Slope and shoved its 25-year-old driver out of the vehicle at around 2:25 p.m., according to the NYPD.

Bullock, 32, then allegedly sped off eastbound on Carroll Street and smashed into a stationary 2012 Mercedes-Benz SUV parked a few doors down, cops said.

He kept going and rear-ended into a yellow 2024 taxi stopped at a red light at Carroll Street and Sixth Avenue — and then plowed into a nearby church fence, causing damage, according to cops.

Bullock then ditched the truck and fled on foot, officials said.

But he bizarrely returned to the crash scene and attempted to climb into a parked New York-Presbyterian Hospital ambulance that responded to the wreck he allegedly created, police said.

Bullock tried to operate the ambulance, but was unsuccessful and was quickly taken into custody, cops said.

He was charged with robbery, attempted grand larceny auto, reckless driving, criminal mischief, and leaving the scene of an accident, according to authorities.
