joined the Brooklyn Rippers, and then the powerful Five Points Gang based in Lower Manhattan. During this time he was employed and mentored by fellow racketeer Frankie Yale, a bartender in a Coney Island dance hall and saloon called the Harvard Inn. Capone inadvertently insulted a woman while working the door, and he was slashed with a knife three times on the left side of his face by her brother, Frank Galluccio; the wounds led to the nickname "Scarface", which Capone loathed. The date when this occurred has been reported with inconsistencies. When Capone was photographed, he hid the scarred left side of his face, saying that the injuries were war wounds. He was called "Snorky" by his closest friends, a term for a sharp dresser.
