NEW DELHI: The Supreme Court 's problem with Covid-19 grew bigger on Tuesday a day after an employee was hospitalized after testing positive for the virus. A large number of security personnel from Delhi police deployed in the complex has been quarantined.The infected employee, from Timarpur area of Delhi who had come to work on April 16, had visited SC 's additional building across the road and had also worked in the main complex. On Monday, two registrars to whom he had carried files, were asked to self-quarantine and work from home.The sources said that deputy commissioner of Police S K Tewari, in charge of SC's security, conducted a thorough contact tracing of the infected employee on Tuesday and found that as many as 36 security personnel at various entry and exit points came in proximity of the person."These 36 security personnel of Delhi police have been sent on quarantine," the sources said.The SC has outsourced sweeping and cleaning work in the premises to a private firm, which deputes 25 people daily amid lockdown. Another batch of 25 people are put on duty the next day. These two batches rotate on alternative days.The DCP on Tuesday found that none of these cleaning staff had masks or gloves which were made mandatory, sources said."Neither the SC nor the contractor had bothered to provide them with basic protection during the pandemic. It was Delhi Police which provided them masks on Tuesday," they added.Sources said not many of the SC staff, who are on duty, have downloaded Aarogya Sethu app, which could have enabled the authorities to trace the infected employee's contacts within minutes."But, the police and authorities had to spend hours scanning CCTV footage of cameras installed at many places to find out the persons who came in contact with the infected employee," the sources said.
