The notorious serial subway saboteur who was busted for viciously shoving a woman face-first into a Brooklyn subway train has been linked to a similar attack in Queens on the same day, police sources told The Post Friday.

Isaiah Thompson, 23, is suspected of pushing a 58-year-old man into an idling southbound F train at the Jamaica-179th Street station at around 7 a.m. Wednesday, sources said.

As in the later incident in Fort Greene, the Queens victim’s face hit the side of the train, and he suffered lacerations to his head.

He was taken to Jamaica Hospital Medical Center for treatment.

The victim, who told police he was spit on and beaten on the platform, also told authorities he recognized Thompson as his attacker after he saw his photo on TV in connection to the other incident, sources said.

Hours later on Wednesday, Thompson — who became infamous for allegedly creating more than 700 subway delays this year by sneaking into conductors’ cabs and pulling the emergency brake — allegedly shoved a woman headfirst into a stationary train in Fort Greene.

Shocking cellphone video of the 7:20 p.m. incident shows the brute jumping up and down screaming, “What!” before he randomly flung the woman into the idling train at the Dekalb Avenue B/Q station.

Thompson was arrested for the Brooklyn attack on Thursday on charges of attempted assault, reckless endangerment, menacing and trespassing, police said.

He was awaiting arraignment Friday for the Brooklyn incident and was not yet formally charged in connection to the Queens incident.

Thompson, who was nabbed five months earlier for allegedly wreaking havoc on the rails, previously told cops that he likes to “create mayhem” on trains by subway surfing and turnstile jumping.
