Supermodel Naomi Campbell failed to turn up as scheduled at a runway show in Brazil on Saturday, apparently after her plans were upset by a conviction the day before for assaulting police officers at Heathrow airport in April.

Campbell, 38, had been scheduled to appear on the catwalk at the Sao Paulo Fashion Show for the summer 2009 swimsuit collection by the Rio label Rosa Cha, according to Globo.com, Terra and other Brazilian media.

But her sentencing on Friday in London to 200 hours of community service and more than 5,600 dollars in fines and compensation seemed to torpedo that modeling assignment.

The British celebrity had admitted in court to kicking and spitting at the officers in a foul-mouthed tantrum as they tried to eject her from a British Airways flight following a row over lost luggage.

Campbell is a regular visitor to Brazil, flying in every couple of months.

Several media in Brazil and Britain have reported that she is involved in a relationship with a Brazilian billionaire, Marcus Elias. The two were photographed kissing while swimming in the Mediterranean last month.
