A day after Mr Anton Casey left Singapore for Perth with his family, his company, Crossinvest Asia has announced that the senior wealth manager is no longer its employee.

In a statement on its Facebook page late Friday night, it said it is deeply concerned that Mr Casey's recent remarks on social media have caused great distress among Singaporeans. "Those comments go against our core corporate and family values that are based on trust, mutual understanding and are respectful of diversity," said the statement.

It said Crossinvest Asia is a family business and Mr Casey's comments "do not represent the culture that we have built over many years". "Accordingly, Crossinvest Asia and Mr Casey have parted ways with immediate effect," it added.

Mr Casey, 39, a Briton married to former Miss Singapore Bernice Wong, caused an uproar when his Facebook post showing him calling public transport commuters "poor people", and another one claiming he needed to "wash the stench of public transport off me" went viral.

The Straits Times reported on Saturday that he and his family left Singapore for Perth on Friday. Mr Casey said it was because of "threats made towards my family". In an e-mail response to The Straits Times, he apologised to the people of Singapore again and offered to do community work "to make amends for my mistakes".
