Freeport Mayor Robert T. Kennedy underwent hip surgery Tuesday evening after being injured in a vehicle crash the day before on his way to a news conference, village officials said Tuesday night.

The mayor, the sole occupant in his vehicle, was cut off by another driver about 11 a.m. Monday on South Ocean Avenue south of Merrick Road as he headed to a conference in the village organized by Sen. Chuck Schumer, said village attorney Howard Colton.

Kennedy could not avoid the crash and was alert following the accident, Colton said.

The other driver, who was not injured, stayed at the scene to wait for the police and later left in his vehicle, the attorney said.

Colton said Freeport police are investigating.

The mayor underwent a “minor operation” at Winthrop-University Hospital early Tuesday night, said village publicist Todd Shapiro.

“The mayor is fine,” Shapiro said. “He’ll be out in the next day or two. He’s doing great.”

Colton said Kennedy had hip surgery, but declined to provide more details: “It’s minor, nothing big at all. . . . We expect him to be fine, no problems.”

Kennedy, 61, has been the village’s mayor since March 2013.
