Fred, the Undercover Kitten who gained fame by posing as a would-be patient to help police nab a phony veterinarian, has died, authorities said Friday.

The tabby was killed Thursday when he wandered into traffic and was run over by a car, according to the Brooklyn District Attorney's Office.

Fred was a rescued stray when he was enlisted by law enforcement in February. He got his due at a press conference, where he sported a tiny badge on his collar.

"He's pretty easygoing, a real Brooklyn guy," his caretaker, prosecutor Carol Moran, said at the time.

Fred received a Law Enforcement Appreciation Award and was honored at an adopt-a-thon benefit hosted by Mary Tyler Moore and Bernadette Peters. He had been "preparing for a new career in education," with a "significant role" in a classroom program that teaches children how to care for animals, the District Attorney's Office said.
