A man who shoved a 71-year-old building landlord down a Queens building’s front stairs — a crime that was captured on a Ring doorbell camera — was indicted on charges of manslaughter and assault on Thursday, officials said.

Alex Garces, 22, can be seen in the video pushing his landlord, Edgar Moncayo, down the stairs so hard that the older man’s head slammed into the concrete sidewalk on 102nd Street in Corona around 2:30 p.m. Jan. 12, prosecutors said.

Garces and a friend then walk down the steps and pass Moncayo’s motionless body on the sidewalk, the video shows.

“This was a horrible incident captured on a Ring doorbell video,” Queens District Attorney Melinda Katz said. “The victim was pushed with so much force it propelled the 71-year-old man over the stairs and onto the pavement, where he struck his head and later died.”

Moncayo’s grandson, Nicolas Jativa, 20, previously told The Post that Moncayo was pronounced dead the day after he was pushed — while on life support with head trauma at NYC Health + Hospitals/Elmhurst.

The tenant initially told cops the fall was an accident that happened as he tried to carry his mattress out of the building and hit the front door, police sources said.

Garces was brought into the courtroom for his arraignment cuffed and communicated through a Spanish interpreter. He pleaded not guilty.

The judge pointed out that Garces has a sentence pending on drunk driving charges that he pleaded guilty to previously.

Justice Kenneth Holder set Garces’ bail at $50,000 bond or $25,000 cash and ordered him to return to court on March 18. If convicted, he faces up to 25 years in prison, officials said.
