(UPDATE) – A maniac possibly disguised as an MTA worker unleashed bloody hell on a Brooklyn subway train during the early-morning rush Tuesday, injuring at least 29 people — including 10 who were shot — when he set off a smoke grenade and opened fire in the car, authorities said.

A jammed Glock and two extended ammo magazines were later recovered at the scene — suggesting the gunman could have unleashed more mayhem if his weapon hadn’t malfunctioned, law enforcement sources told The Post.

The shooter — who has been on the run for hours — was wearing a “green construction-type vest” and gas mask when he launched his bloody assault aboard a Manhattan-bound N train around 8:24 a.m. just as the subway was pulling into the 36th Street station in Sunset Park, NYPD Commissioner Keechant Sewell said during a news briefing at the scene.

“An individual on that train donned what appeared to be a gas mask. He then took a canister out of his bag and opened it,” Sewell said. “The train at that time began to fill with smoke. He then opened fire, striking multiple people on the subway and on the platform.”

New York City Mayor Eric Adams told local affiliate FOX 5, New York, on Tuesday that investigators are pursuing “several leads” and feel confident that they will make an arrest.

“We’re unsure of the motive or exactly where he came from, but we are carrying through on several leads,” Adams said. “We feel confident that we’re going to apprehend this person.”

Adams would not answer additional questions surrounding the U-Haul van that was found about 5 miles away from the crime scene and is alleged to be linked to the suspect. He also wouldn’t say whether the suspect is believed to be a New Yorker or from out of state.

Asked about surveillance footage from inside the subway station that malfunctioned, Adams said he does not yet know what happened, but added: “We’re looking into it … We’re still trying to identify exactly what happened with the video feed at the location.”
