On 12 March 1993 , a series of 12 bomb blasts took place in Mumbai , Maharashtra . The attacks were carried out in retaliation for the Bombay riots that occurred earlier in the year . They resulted in 257 deaths and 713 injuries . Anurag Kashyap 's feature film directorial debut '' Paanch '' ran into censorship trouble and had been shelved when Arindam Mitra , director of operations for '' Mid Day '' , approached him with the book '' Black Friday : The True Story of the Bombay Bomb Blasts '' written by Hussain Zaidi , their chief crime correspondent . He wanted Kashyap to write a television series based on it for '' Aaj Tak '' , to be directed by Aditya Bhattacharya . Kashyap read an unedited version of the book , which had not been released at that point , and was " fascinated " by it . He wrote the script in episodes for the mini series but later felt it was better suited as a feature film
