A Staten Island woman was indicted for fatally mowing down two Park Slope children — including the daughter of a Tony Award-winning actress — in March, law enforcement sources told The Post on Wednesday.

Dorothy Bruns, 44, was hit by a Brooklyn grand jury with charges of manslaughter, criminally negligent homicide and assault stemming from the horrific March 5 crash on Ninth Street near Fifth Avenue, sources said.

Bruns told cops she had suffered a seizure, causing her to lose control of the car shortly before she fatally ran over Joshua Lew, 1, and Abigail Blumenstein, 4, the sources said.

The kids were crossing the street with their moms, including Abigail’s mother, Ruthie Ann Miles, who won a Tony for “The King and I.”

Bruns has racked up 12 violations since 2016 for a slew of offenses, including speeding in school zones and running red lights.

Mayor Bill de Blasio, who has made pedestrian safety a priority, lashed out at Bruns at the time, saying, “She should never have been allowed to be driving a car after what we know of these other violations.”
