Road rage brawl leads to knife injury for 20-year-old man in Queens.

A 20-year-old man was slashed in both arms after a road-rage incident that led to a crash on a snow-slicked street in Queens, officials said. The victim told cops that he and his three friends were in a Ford SUV motoring down 108th St. near the Horace Harding Expressway at 1:20 a.m. when a 1999 Suburban with four people inside rolled up alongside. The driver of the Suburban started threatening the Ford driver, officials said. As the two argued, the Ford operator lost control of the vehicle, which ended up on the sidewalk and hit a fence, officials said. Both groups tumbled out and jumped each other, sparking a brawl that ended with the 20-year-old suffering deep gashes in both of his arms. Everyone except the wounded man ran off before paramedics could take him to Elmhurst Hospital. Cops were investigating the attack Wednesday.
