Drug dealer tosses weed off Brooklyn rooftop, causes free-for-all on street below

A drug dealer tossed an entire bag of weed off a Brooklyn rooftop during a deal gone wrong — causing a free-for-all on the street below, as passersby scrambled to load up on free pot, authorities said.

The 29-year-old man arranged to meet with several people on the rooftop of a Sunset Park building around 11:15 p.m. June 1 to sell them marijuana, police said Tuesday. But when he arrived, the crew allegedly displayed a gun and jumped him as they attempted to snatch the bag filled with weed, cops said.
