MANHATTAN — A woman shoved a 70-year-old man onto subway tracks at the Union Square station Wednesday afternoon, prosecutors said.

Sandra Zelazny, 32, pushed the man about 5:30 p.m., leaving him with a bloody cut across the forehead, according to the Manhattan District Attorney's office.

He was treated at Bellevue Hospital, prosecutors said.

Zelazny was arrested and charged with assault and reckless endangerment, according to prosecutors who said she showed "a depraved indifference to human life."

There was no indication that Zelazny has a criminal record in New York, according to a Department of Corrections and Community supervision spokeswoman.

She was held on $30,000 bond and was due back in court on Monday, records show.
