A facebook user drew flak for mocking Miss Philippines Megan Young, 23, for winning the Miss World 2013 in Bali on Sept 28.
Her comments, posted on her Facebook social networking timeline, invoked the ire of netizens and prompted one Singaporean to lodge a police report.
She had posted: "Miss Philippines is Miss World? What a joke! I did not know those maids have anything else in them Ha Ha Ha." The post attracted 20 likes and 468 shares within a day.
It's unclear when she made the post as a search for the Facebook account turned up a message that said the page was unavailable. It is likely the page was removed, reports The New Paper.
But outraged netizens were able to capture screenshots of the post and its comments before the account was deleted.
Others have tried to establish her identity. Her LinkedIn networking website account is believed to have also been deleted.
The screenshots have been re-posted on other websites with scathing responses to her post. Many defended Filipinos.
Someone replied to her post by saying, "Filipino girls are cute, humble and honest as far as I know. I am glad to have great friends from the Philippines."
But that invited a reply from her: "They are poor, smelly from cleaning toilets and uneducated."
When another netizen hinted that she is ignorant, she replied: "Ignorant? Get ur vocabulary checked. Majority are maids and one won such a title! It's shocking & dumb!"
The police confirmed that a police report was made and they are looking into the matter.
A Singaporean, who wanted to be known as Mr Anthony, confirmed that he had made the police report on Thursday at about 1pm.
The 27-year-old civil servant told The New Paper: "I'm concerned with the comments made by this person, especially when racial harmony is threatened and I see this being spread online.
"Racial harmony is very important and these kind of comments should not be tolerated." He said that he first read about the posts on a forum.
He then logged into his Facebook account and saw screenshots of the comments that have been re-posted.
He said: "I want to inform the police that there's such a thing and for them to find out, if there's any offence committed."
