The man who entered the track during the Singapore GP has been jailed for six weeks.
27-year-old British national Yogvitam Pravin Dhokia was arrested and charged with committing a rash act as to endanger the personal safety of the drivers after climbing over the fence and walking along the track as the cars sped past.
"The accused's act was not only rash but was both selfish and foolhardy," District Judge Chay Yuen Fatt said, adding that Dhokia had admitted he had wanted to film the race from the track.
"Any dangerous intrusion onto the race track can and could have resulted in disastrous and fatal consequences."
Dhokia's lawyer Shashi Nathan told the court that his client's actions were "a childish endeavour" and he did not intend to disrupt the race or spoil the spectacle, according to the Singapore-based Channel NewsAsia news channel.
