A 30-year-old man, suspected to be mentally ill, jumped from the 19th floor of an SRA building at Kalanagar, Bandra East, on Friday noon. Rajendra Kedare, a resident of Ambedkar Garden slums in Shashtri Nagar, had climbed on to the extension rods of the 19th floor of the building. For nearly 30 minutes he was up there sitting on the rods, trying to balance himself. Suddenly, he leaned out and fell, says a woman who resides in the building.
