CHENNAI, India (Thomson Reuters Foundation) - Shoppers at malls in Bengaluru may have gotten more than they bargained for on Labour Day, as campaigners used the occasion to highlight the plight of victims of modern slavery.

Screens with images and information about bonded labour joined advertisements for Labour Day sales in at least four popular malls in Bengaluru.

Shoppers were encouraged to snap selfies in front of the digital displays and post them to social media in order to raise awareness of the crime, so they would be more likely to recognise and report it.
