Stranger punches man, breaks nose in unprovoked subway attack in Brooklyn

A stranger repeatedly punched a 64-year-old man — breaking his nose and fracturing his face — in an unprovoked attack inside a Brooklyn train station over the weekend, cops said.

The victim was on a Manhattan-bound R train at the Prospect Avenue station just after 1 p.m. Sunday when the assailant approached and began pummeling him, police said. The suspect bolted from the train at Prospect Avenue.
