The man, identified as Rahul Rajnikant, was seen by an eyewitness, who told the police that he had earlier gone to the seventh floor twice.
A police official said that Mr Rajnikant had allegedly finished eating his lunch and then went back again for the third time, which is when he leaped to his death.
Mr Rajnikant was residing in the Golf Course area of Gurugram and managed a restaurant in Supermart 1 in DLF Phase 4. The building from which he jumped, was the same building where his restaurant was located.
Police officials said Mr Rajnikant belonged to Indore in Madhya Pradesh, whereas his wife and daughter are said to be living in the US.
