There were seven boys and four girls at the party which began at around 11 pm.

He went to bring something from the kitchen, but friends at the party soon heard a loud thud. Dhwanil had jumped from the kitchen window and had fallen 19 floors below on the ground.

Sources said, Dhwanil had a tiff with his ex-girlfriend, who had returned from London to join the party at Jahnavi's home.
