A knife-wielding man on parole for attempted murder, identified as Darryl Jones (DOB April 1990), randomly attacked a Hassidic couple walking with their 1-year-old in Lower Manhattan on Wednesday — slashing all three family members, cops and police sources said.

Video footage obtained shows the family of three was taking a stroll on State Street near Battery Park at about 5:50 p.m. when the maniac passed by — and then turned around and came at them with a blade, according to sources and the NYPD.

He slashed the father on the head, the mother on the lip and the baby on the chin, the officials said.

The unhinged creep ran after the family, who fled with their baby in a stroller, the sources said.

All three of the victims were treated for minor cuts by first responders on the scene and declined further medical attention.

A 30-year-old parolee was arrested in the assault and cops recovered the knife after canvassing the area, the sources said.

The man was released from jail last month. He spent several years behind bars after pleading guilty to attempted murder tied to a violent August 2011 robbery on the Upper East Side, according to the sources.

Charges were pending late Wednesday and an investigation was ongoing.
