The police are investigating a Twitter user for making racist remarks on the social networking portal.

The woman, who goes by the handle 'iamclarena', had recently posted a series of racist remarks against Indians with her Twitter account.

Responding to queries from The Straits Times, the police confirmed on Friday night that a report had been lodged against the woman for making racially aggravating remarks on social media.

The woman, who also goes by the handle 'Clarena Clanen TzeYi' on Facebook, is the second person this week to be investigated for posting racist remarks on the Internet.

The police had said earlier that a 22-year-old man is under investigation for making racially insensitive remarks on Facebook while posing as a woman with the fictitious name of Heather Chua.

The comments targeting Malays last week caused an outcry among netizens, and led to several police reports being lodged.
