An investigation has been launched after a group of migrant workers were filmed being doused in a "chemical solution" by Indian officials.
They are understood to be migrants who returned to the city of Bareilly, in the northern state of Uttar Pradesh.
They are among millions who have returned to their home villages amid a nationwide, three-week lockdown.
The move is supposed to stop the spread of coronavirus, but there are fears the returnees may spread the virus further.
The video - which has been viewed nearly 400,000 times after it was uploaded by a Times of India journalist - shows the group squatting on the ground while medical and fire department officials dressed in hazmat suits spray them with a "chemical solution".
Who r u trying to kill, Corona or humans? Migrant labourers and their families were forced to take bath in chemical solution upon their entry in Bareilly. @Uppolice@bareillytraffic @Benarasiyaa @shaileshNBT pic.twitter.com/JVGSvGqONm— Kanwardeep singh (@KanwardeepsTOI) March 30, 2020
In the full video seen by the BBC, the officials shout instructions over a megaphone asking the workers to close their eyes and mouths. In another part of the video, an official can be heard ordering the group to "close the eyes of your children and close your eyes too".
Bareilly's district magistrate said the video had been investigated, adding on Twitter that "the affected persons... are being treated under the supervision of the Chief Minister's Office (CMO)".
"The team of the Bareilly Municipal Corporation and fire department officials were asked to sanitise buses but in their enthusiasm they sprayed the workers too," he wrote.
Several accounts then began to emerge of the harassment of migrant workers leaving the capital at the hands of the police and local administration.
The video has caused an uproar on Twitter, with many users asking if passengers landing in India were "disinfected" upon arrival, and pointing out that it is not protocol at airports, bus stations or train stations.
What on earth is this? Am sure this isn't done at the airports, where the Coronavirus came in, or at quarantine centres.... https://t.co/iSQ08FluWc— Suhasini Haidar (@suhasinih) March 30, 2020
Utterly shameful of local officials in Bareilly: ‘chemical bath’ by spraying disinfectants on returning migrant workers instead of on the bus. Officials have been suspended now after video went viral: exposes the mindset of authorities when dealing with the poor. pic.twitter.com/fuenv5z5DU— Rajdeep Sardesai (@sardesairajdeep) March 30, 2020
This is not the first video showing apparent mistreatment of migrant workers to emerge since the lockdown was announced on 24 March.
Most of them are daily-wage workers who are now out of work. In the absence of money and jobs, they are desperate to reach their villages. Some found government-run buses to reach home and others just continued to walk.
