A teenager was mugged at knifepoint in Central Park, police sources said Monday.

The 17-year-old told cops he was walking at East Drive and the 85th Street Transverse at about 11:50 p.m. Sunday, when he was approached by two men.

One of the thugs threatened him with a knife and demanded money, the other came up from behind and punched him in the back of the head.

When he fell to the ground, both men punched and kicked him, the sources said.

The boy handed over his wallet, which contained $150, and his Samsung phone, the sources said.
