A woman robbed a straphanger at knifepoint inside a lower Manhattan subway subway station during Wednesday morning rush-hour, police said.

The victim was on the 2/3 train platform at the Fulton Street station around 9:30 a.m. when the mugger flashed a knife at her and grabbed the contents of her purse, according to the NYPD.

The suspect then ran off and was in the wind Wednesday afternoon, cops said.

No additional information was immediately available.

The robbery came the day after a 34-year-old woman was shoved onto subway tracks by a stranger while waiting on the 1/2/3 train platform at Chambers Street.

Good Samaritans rescued the unsuspecting woman, pulling her off the tracks as her attacker fled.

It also follows a violent weekend in the city’s underground, where a train operator was beaten by a pipe-wielding assailant, and a subway rider was stabbed by a stranger.
