Police are looking for two people they said repeatedly punched a Brooklyn subway conductor Saturday after he announced the train was going express — an attack caught on camera.

It happened around 4:40 a.m. on the A train platform at the Grant Avenue station in Cypress Hills.

NYPD officials said the 62-year-old conductor announced that the train would be making express stops, and then a man approached the conductor's booth window and started yelling at him and throwing punches.

Bystander video released by the NYPD shows a man reaching through the open window before the conductor tries to push him away. As they grapple, a woman is seen hurling punches through the window.

Police said three people had complained that they had missed their stop before one of the attackers threw beer cans at the conductor, who was treated for cuts and scratches to his face and arms.

The city police department has not made any arrests at this time.

The male attacker was last seen wearing a red shirt and gray pants, while the woman was last seen wearing a gray dress and glasses.
