Sharing the news, writer-director-media strategist and a close associate, Anusha Srinivasan Iyer, told IANS that he was suffering from cancer.
Katyal was admitted to the Shanti Avedana Ashram located in Mount Merry, Bandra, where he died.
Iyer said: "Brijji was all of sixteen even as an octogenarian. His energy was infectious. I took my baby steps into writing assisting him in penning his scripts... He was always wanting me to direct, finding producers for me. When my short film 'Saare Sapne Apne Hain' travelled to 53 festivals, he was happier than me."
Katyal also wrote the story of many TV serials including 'Dillagi' and 'Saans' which was directed by Neena Gupta.
Renu Sharan, one of the producers who worked with Katyal, said: "He wrote many scripts for us, the first being 'Dillagi'. His characters were very real."
