Singapore authorities have rejected reports that Maurizio Arrivabene was detained and fined for discarding a cigarette butt last week.
The city state's stance on street littering is infamous, with stringent enforcement and harsh penalties in place for infractions.
However, the local Channel NewsAsia contacted Singapore's National Environment Agency (NEA) and said that the reported incident involving Arrivabene never happened.
"Reports in the international media on this matter are bogus," the agency reportedly said.
Singapore authorities also played down reports that last weekend's night race saw the lowest ever spectator turnout in the event's nine-year history.
"That's really more a reflection of the global environment in terms of economic uncertainty and so on," government minister S Iswaran is quoted as saying by the local Today publication.
"It's a little bit like in 2009, when you had the global financial crisis. There was a major correction and then it went up again quite strongly."
The season continues next weekend in Malaysia.
