A tuxedo-clad man walking near Wollman Rink in Central Park early today was mugged and slashed in the hand by a group of thugs, authorities said.

The violence erupted at 12:31 a.m. just outside the rink near the Central Park Zoo.

The man, described as in his 30s and dressed up in a tuxedo, had lost his glasses and “couldn’t see properly,” according to one cop at the scene.

As the man stumbled by the rink, he was jumped by a group of men who sliced him in the hand with a knife, and then stole his wallet and an iPod, the officer said. The muggers fled.

The man’s injury was not serious, the officer said.
