In the 1970s, Dawood Ibrahim worked for a local smuggler named Bashu Dada. Bashu Dada had a close friendship with Dawood's father, who was a police constable. His father wielded immense clout among the gangsters and common people due to his sense of morality and justice, while also being a part of the Crime Branch. However, Bashu Dada and Dawood had a falling-out after Bashu Dada insulted the latter's father. In 1976, Dawood – along with seven of his close friends and his elder brother Shabir Ibrahim Kaskar – attacked Basu Dada with empty soda bottles, a first in the history of gang warfare in Bombay.
