A World Cup bus was set alight and a teenager suffered a gunshot wound during chaotic scenes in Midtown Manhattan as thousands of basketball fans poured into the streets late on Saturday to celebrate the New York Knicks’ historic win in the NBA Finals . Some fans set off fireworks and fired smoke grenades after spilling out of packed bars and outdoor venues, chanting “Knicks in five!” to mark their team’s victory in the fifth game of a possible seven. The New York Knicks have not won a title since 1973, and this was just their third appearance in the finals after losses in 1994 and 1999 — to the Houston Rockets and the San Antonio Spurs, whom they defeated on Saturday night.
