Three MTA workers were assaulted in two “reprehensible” incidents within two hours of each other Friday in Manhattan, officials said.

In the first incident, a “young kid” slugged a subway conductor in the face around 12:50 p.m. just as he was pulling out of the 125th Street station on a northbound A train, police said.

The conductor was taken to St. Luke’s Hospital with swelling to the face, cops said. The kid fled the scene.

At 2:30 p.m., a motorist threw a glass bottle at an M5 bus driver’s window at 136th Street and Broadway, police said. The bottle shattered the window, leaving the 36-year-old bus driver bloodied with cuts to the nose and left ear. An off-duty driver, 34, who was also on board suffered a minor cut to the left ear.

Both were taken to Columbia-Presbyterian Hospital, while the suspect fled the scene in a black Ford sedan.

“The pattern of unprovoked attacks on transit workers is reprehensible,” said Robert Diehl, NYC Transit’s senior vice president of safety and security.
