SINGAPORE: Anton Casey, a British expatriate whose derisive comments about Singapore's public transport have stirred public anger, is no longer with his employer Crossinvest Asia.

In a statement on its Facebook page in the early hours Saturday, wealth management firm Crossinvest Asia said it had parted ways with Casey with immediate effect.

The firm said it was deeply concerned by the Briton's recent comments on social media that "have caused great distress amongst Singaporeans".

It said those comments go against its "core corporate and family values that are based on trust, mutual understanding and are respectful of diversity".

Porsche-driving Casey, 39, who is married to a former Singapore beauty queen, has gone to Australia but has not said what his future plans are following the controversy.

He holds permanent residency in Singapore, which he calls his adopted home, and claims to have received death threats after he referred to public transport users as "poor people" in a social network post on Monday.

The Briton and his family, now in Perth, faced stinging verbal abuse from Internet users after Facebook posts insulting commuters in the city-state went viral.

Many took to the social media on Saturday to welcome Casey's departure from the boutique wealth management firm.
