An unidentified Freeport, Long Island man died on the tracks at the Bellmore LIRR station early Saturday morning. Officials tell the Post the man was electrocuted by the third rail, and investigators believe that 34-year-old Roosevelt resident Niheim Levy "exchanged heated words with the ­49-year-old victim before robbing and pushing him to the tracks at about 5 a.m."

At first it appeared that the victim suffered a seizure and fell on the tracks, but a subsequent investigation suggested foul play, and Levy was arrested yesterday. Levy, whom Newsday reports has worked for a moving company the past 12 years, has previous arrests for criminal mischief and false personation. Police sources tell Newsday that a verbal dispute between the victim and Levy turned into a fight, and the victim fell onto the tracks.

The MTA has not officially confirmed that the victim died from electrocution. A spokesman tells us "the cause of death is under investigation (it may or may not have been electrocution). Whether there was a robbery is also under investigation."

Levy is now on suicide watch, Newsday reports.
