The police are investigating a Facebook post showing a black T-shirt with a graphic of the Singapore flag being ripped apart by a pair of hands to reveal the Indian flag underneath.

The image, which is believed to have first surfaced on Aug 14, one day ahead of India's Independence Day, was widely shared online when it was posted onto the Singapore Indians and Expats page on Facebook by Singapore permanent resident Avijit Das Patnaik. The page has over 11,000 members.
