Cops busted the teen who stole an SUV from a Brooklyn street while a 1-year-old was sitting in the backseat, officials announced Friday.

Quansae Herring, 17, was collared late Thursday — weeks after hopping into the Mitsubishi Outlander on Aug. 5 from Kingston Avenue near Dean Street in Crown Heights, where the boy’s mother had left him in the car while she went into a nearby grocery store, cops said at the time.

Herring then ditched the SUV — and the baby — just over a mile away at 1617 Park Place, police said.

Later that week, cops released photos and a video of their suspect.

Herring was charged Thursday with grand larceny, criminal possession of stolen property and acting in a manner injurious to a child, cops said Friday.
