Authorities in Mumbai's Dharavi slum - home to one million people - are turning to increasingly harsh measures to enforce coronavirus lockdown rules; residents say they are often beaten if they leave their homes, and surveillance drones hover overhead.
The Covid-19 pandemic is expected to hit India hard. With 23,452 reported cases and 723 deaths, hospitals across the country are already overwhelmed.
With poorly ventilated, dense housing, populations in slums like Dharavi are expected to be badly affected by the virus.
But residents of Asia's largest slum, perhaps best known as the setting for rags-to-riches blockbuster Slumdog Millionaire, are worried they are being treated like "animals" as authorities consider testing an unproven drug linked to heart attacks on them in a bid to find a cure for the virus.
Javed Shaikh, a local tour guide who has lived in Dharavi his whole life, says food is scarce and police attack people with sticks when they venture out of their cramped homes.
Shaikh, like many of the slum's citizens, lives with five family members in a home that measures 9sq m.
"It's very very tiny. It's like a small cage," he tells The Sunday Telegraph.
Drones now circle over the corrugated iron rooftops to monitor activity in hard-to-access pockets of Dharavi, making residents nervous.
"Police flew a drone over our neighbourhood and saw some people sitting outside collecting water," one resident, who wishes to stay anonymous, says.
"So they came and started hitting people with their sticks. I was standing in the doorway and they pushed me inside."
As the number of confirmed coronavirus cases in the slum increases daily - up to 214 as of Thursday night - the local economy has come to a standstill as authorities ratchet up containment efforts.
As part of these efforts to stop the pandemic, Mumbai city officials are considering testing anti-malarial drug hydroxychloroquine as a prophylaxis - where medicine is given to healthy people to prevent infection - on groups of people in Dharavi and another nearby slum.
The drug has been touted by Donald Trump, the US president, as a "game changer" for the coronavirus, but it has not been proven to significantly treat the virus and it comes with serious side-effects including increased risk of heart attacks, nausea, and blurred vision.
Sabina Khan, who lives in Dharavi with her son, is wary about the trials.
"I don't feel right about it, we're not animals," she says, adding: "But this kind of thing is not new for us."
Vinod Shetty, a human rights lawyer and founder of Acorn Foundation, an NGO that works with slum dwellers, says: "Residents feel they will be treated badly, as usual. And that comes from their long experience with public hospitals and authorities."
Dharavi is a vibrant community and an economic powerhouse in Mumbai, with an annual economic output of $1bn. Prior to lockdown, its inhabitants worked in Dharavi's thousands of factories or fanned across the city to serve as labourers and domestic staff.
Shetty says governments have depended on Dharavi for labour to transform Mumbai into a global city, but little has been done for the neighbourhood's residents.
"They live in conditions like 1920s England," he says.
Narendra Modi, India's prime minister, was praised by some for swiftly implementing the lockdown on India's 1.3 billion people in March, but many have pointed out the tactic disproportionately affects the poorest. Just under half of Mumbai's population live in slums like Dharavi.
Social distancing is all but impossible and containment is an uphill task. Lack of infrastructure means hundreds of people rely on community toilets and throngs of people stand in line to purchase food at the markets, which are only open for a few hours each morning.
Khan says "shopkeepers are raising prices day by day" and staple products such as matchboxes, rice and nuts are more expensive now.
Many people in Dharavi - including thousands of migrant workers - lack a government-issued ration card that would entitle them to small amounts of rice and wheat flour.
Laxmi Kamble, a Dharavi resident, is unable to access her government allotment because her name is listed on her ex-husband's ration card and she does not have her own.
Residents say they have received little help accessing food.
Shetty says Acorn Foundation members have distributed more than 7000 meals within Dharavi, but he is worried about how to keep everyone safe.
"There is a constant danger that our volunteers and staff are being exposed to coronavirus."
Municipal officials say they are working to increase the food supply in Dharavi, and have distributed more than 20,000 packets of groceries so far.
According to Kiran Dighavkar, assistant municipal commissioner who oversees Dharavi, officials have focused on five "red zones" where the majority of cases are located; these areas have been sealed from the general public, and food and medicine are being delivered to each family's doorstep.
A group of more than 20 doctors, many of them volunteers, have gone door-to-door to conduct thermal imaging scans of 50,000 people.
The government is also rapidly working to expand its quarantine capacity, from 1200 beds to 2000 beds within the next few days.
For Shaikh, the tour guide, there is little to do now except wait for the lockdown to end on May 3. He hopes it will not be extended again, but that remains a possibility.
"It's a difficult time for all of us," Shaikh says. "We have to control the virus, so we stay at home. But we should do something fast, so that we can go outside again. And go to work."
