The March knifepoint robbery of a 72-year-old woman in Greenvale was solved when police said DNA linked the crime to a man from the Bronx.

Benis Solis, 24, of East 184th Street, was arrested at his home Wednesday and charged with first-degree robbery and third-degree criminal possession of a weapon, Nassau County police said.

At arraignment Thursday in First District Court in Hempstead, Solis was ordered held on $100,000 bond or $50,000 bail, according to online court records. He is due to return to court Monday.

The man then pushed the woman "halfway into the vehicle," police said, "forcibly" removing her ring, before fleeing on foot.

The robbery occurred at about 6:30 p.m., police said.

Police said Solis was connected to the robbery through DNA, but declined to provide further details on what type of evidence was left or how it was connected to Solis.
