A 20-year-old student from Bengaluru committed suicide by jumping from the 19th floor of a top hotel in Mumbai after posting a video on Facebook, describing the step he was taking to end his life, police said on Monday.

The victim, who succumbed to the fall instantly, has been identified as Arjun Bharadwaj, who was studying in a prominent Mumbai college. 

Arjun hails from Bengaluru and is son of a businessman.

In the video, which has now been pulled down by Facebook, Arjun describes 'how to suicide', and says, step 1 is to write notes to people. Arjun was drinking in the video, and showed the notes he had written to his family and friends. 

He switched off the video before reportedly smashing the glass window and jumping off the 19th floor room.

"We have recovered a suicide note which indicates that he was disturbed. We are investigating further," Joint Police Commissioner Deven Bharti told IANS.

The social media profile of the youth is being checked by police to asertain the motives behind the drastic measure while his family has been informed of the tragedy.
