Four men have died in New York's subway in less than 24 hours.

Police say the mishaps -- all on Saturday -- are unrelated.

The first victim was found unconscious at about 2 a.m. in Queens' Elmhurst Avenue station at Broadway, on the R line. Police say he may have fallen down the stairs. He reportedly was in his 60s.

At about 8 a.m. Saturday in Manhattan, a man in his 20s was struck by an L train at West 14th Street and Third Avenue.

Another man also was hit by an L train on the same line on Saturday evening.

The fourth fatality was reported in Brooklyn, when a man's body was removed from the tunnel near the Nostrand station on Saturday afternoon.

The victims' identities were not released.
