A group of giant rats has invaded Marcy Projects and one man is fighting back. A Housing Authority worker named Jose Rivera speared one of rodents with a pitchfork this week, which makes him the ghetto warrior of the year. The rats are about three feet long and have supposedly lived there for six years. The New York Daily News interviewed a woman who said that the rat pack tends to “get together and gang up on the cats.” This is the stuff nightmares are made of.
