Cops are searching for two teenage boys who jumped into the Hudson River in Inwood on Friday afternoon — and never resurfaced, police sources said.

The teens, both aged 13, were believed to be playing around when they removed their clothes and leaped into the river from a railway bridge near the Dyckman baseball fields in Inwood Hill Park around 5:45 p.m.

One of the boys was seen “struggling” in the water at one point, an NYPD spokesman said.

Police continued to canvas the area off Dyckman Sreet and the Henry Hudson Bridge into Friday night with boats and helicopters.
