The lockdown has left numerous migrant workers jobless and scared they won't be able to afford food or other essentials, according to the AP.
So far, 40 cases of coronavirus have been reported in the national capital.
Uttar Pradesh Chief Minister Yogi Adityanath has arranged about 1,000 buses to help UP-Bihar migrants from Delhi return to their villages, official sources said here on Saturday.
Thousands of daily wagers and labourers from Delhi, Haryana and even Punjab reached Anand Vihar, Ghazipur and Ghaziabad's Lal Kuan area after taking arduous treks of many kilometers on foot to take buses to their respective native places.
A family makes its way back home from Dehi trekking hundreds of kilometres during the lockdown. "We have also provided some DTC buses to transport them".
"We have no count of how many of them would have crossed (into Uttar Pradesh) since Wednesday but they keep coming all through the day", a police officer on patrol duty at the border said.
"Many migrant workers feel they have no choice but to walk home".
Puranam said Delhi's homeless shelters are overflowing with people and the state government has made a decision to convert public schools into shelters from Sunday. "I urge people to stay put where they are".
Notably, after the sudden announcement of the lockdown by Prime Minister Modi, migrant workers who were left without jobs, shelter and food were spotted walking towards Delhi-Ghaziabad border as the government had suspended all interstate bus and railway services to contain the spread of coronavirus.
With the Uttar Pradesh government making several attempts to remove the protesters from the protest site, CM Adityanath's government has been brutal against the protesters who have largely been staging sit-ins peacefully against the CAA.
Besides, the Union Home Ministry also directed state and union territory governments to provide "adequate support" to migrant workers.
