A man is recovering after being slashed with a machete in Sunset Park, and the people responsible have not been caught. This happened just after 4 p.m. Monday outside a building on 5th Avenue. A 34-year-old man was on the sidewalk when he was slashed in the back during some kind of dispute. A police source tells News 12 the weapon used was a machete. He was taken to the hospital and is expected to be OK. The two men involved ran off and have not been found. One was last seen wearing gray clothing with a backpack. The other was wearing a black hoodie with a crossbody bag. Right now, investigators are still working to figure out what led up to the dispute. This remains an active investigation.
