TROY — A city resident who was paroled from state prison earlier this month after serving a sentence of almost seven years on drug and assault charges was arrested Saturday after allegedly tackling an elderly woman to the ground during the Troy Waterfront Farmers Market.

Naquan Ruiz, 29, was arrested for third-degree assault, a misdemeanor, after what a Troy police spokesman characterized as the unprovoked attack during the popular market, which throngs with thousands of people on Saturday morning and early afternoon.
