A 46-year-old German tourist fell to his death from Marina Bay Sands Skypark on Tuesday afternoon.
This is the first time such an incident has happened since the SkyPark's June 2010 opening.
Chinese daily Shin Min Daily News said the man was found on a grass patch in front of the integrated resort and that he was already dead when police officers and Singapore Civil Defence Force responders arrived.
MBS deployed more than 10 staff to seal up the area and prevent passers-by from gathering.
A black screen was erected in front of the scene. Security officials were also posted to prevent unauthorised access.
The officials said renovation works were going on when questioned by the Chinese daily's reporter.
It is understood that the deceased is not a hotel guest, but one from another nearby hotel.
Two German embassy officials who were at the mortuary declined to comment.
The police have classified this incident as a case of "unnatural death" and are investigating.
The Marina Bay Sands SkyPark is 57 storeys high and sits at more than 200m above ground level.
