NEW DELHI: Leaked WhatsApp messages from a group administered by a Delhi government official who faces disciplinary action for " dereliction of duty " is being investigated by intelligence agencies as it points to actions which were at odds with the 21-day lockdown announced to stop the spread of coronavirus.Sources at the Centre said contents and the dates of the messages coincided with the surge of migrants on Delhi roads who were seen moving towards the borders with UP and pointed to actions meant to facilitate or encourage the flow of workers during the weekend.Four Delhi government officials face action for failing to carry out lockdown orders and putting public health at risk. Renu Sharma, additional chief secretary, transport department, and Rajiv Verma, principal secretary, finance, were suspended. Satya Gopal, additional chief secretary, home and land buildings department, and Ajay Kumar Arora, SDM, Seelampur, were served show cause notices.The agencies, which are collecting information on the migrant movement in the capital, are looking at reports and videos of announcements made in certain areas asking people to move to the borders where it was claimed buses were available to take them further to UP and Bihar. The availability of DTC buses to move migrant workers in large numbers to the border is also being investigated.The WhatsApp communication, however, points to an effort to take people on the roads to certain points for onward journeys. Home ministry officials have held that the actions, in contravention of the lockdown orders, amounted to a sabotage of the effort to contain the coronavirus infection spread. Sources said the Centre's displeasure was bluntly conveyed to the UT administration on Saturday evening as thousands of migrants swamped inter-state bus depots.There have been migrant movements in other states and cities as well, but the events in Delhi are being seen in a different light by the Centre which feels that officials charged with implementing the lockdown order failed to do so and perhaps acted with deliberation. Delhi government has not reacted to action taken by the Centre against its key functionaries.TOI reported on Tuesday that lieutenant governor Anil Baijal had also expressed unhappiness over the migrants being allowed to move outside the city despite the lockdown.The largescale of movement of migrants has presented central and state health authorities with the challenging task of tracking workers to their villages and hometowns. Bihar, home to thousands of migrants, is indignant about the "breach" of the lockdown and has struggled to figure out ways to deal with the return of hundreds of potential carriers of coronavirus.
