#Suspected subway saboteur charged for causing train derailment: cops

The man suspected of causing a Manhattan subway derailment by tossing metal construction debris onto the tracks was hit with a number of charges for the vandalism on Sunday night, police said.

Demetrius Harvard, 30, is accused of chucking the material onto the tracks at 14th Street and Eighth Avenue as an uptown A-train was pulling into the station at about 8:20 a.m, authorities said.

The suspected subway saboteur was hit with reckless endangerment, criminal mischief, assault and criminal trespass charges in the incident that created delays to the transit system, officials said.

The first car of the train veered off the tracks, sideswiping at least 10 beams after striking the metal ties, also known as D plates.

All 135 passengers were taken off the train by first responders. Three of straphangers reported minor injuries, the FDNY said.

Harvard allegedly tried twice to chuck the metal debris onto the tracks Sunday morning, sources said.

After he allegedly threw the material onto the tracks a first time, a good Samaritan went down and retrieved them, sources said.

But he allegedly picked them up and hurled them back just as a train was pulling into the station, sources said.

Harvard found the plates among construction materials at the station, police sources said. MTA workers have been warned not to leave the items close to tracks or near where riders could get a hold of them.

Straphangers held Harvard until cops arrived.

Harvard was previously arrested Sept. 5 on charges of criminal mischief for allegedly hurling a metal bench through a bus window on 8th Avenue and 22nd street, according to sources and records. He was released without bail in that case.
