A 75-year-old woman was robbed and shoved to the ground by a female thief on a Manhattan train last week, cops said.

The elderly victim was on a southbound No. 6 train at the 14th Street/Union Square station Thursday at around 4:35 p.m. when a woman snatched her purse off the floor. When the victim tried to stop the thief, the mugger pushed her to the ground before taking off.

The purse contained the victim’s cell phone, bank cards and approximately $100 in cash.

The robber was last seen wearing a black hooded sweater, blue jeans and white sneakers.
