Delhi Police had found a IAF Sergeant was near Nizamuddin Markaz during religious congregation. He was traced after his mobile phone was located over.

Police later informed the force and thereafter IAF Sergeant was placed in quarantine. It was also found that two IAF personnel came in contact with the Sergeant so both of them were also sent to quarantine as per standard operating procedures.

The religious congregation at Delhi's Nizamuddin organised by Tablighi Jamaat sparked off nationwide search for its attendees with reports emerging from various states of new clusters of coronavirus infected people linked to the event.

The congregation was organised by Mohammad Saad, the Tablighi chief, wherein workers from 41 countries took part and later went to different parts of India.

It has been found that over 95 percent of the coronavirus cases reported over the last two days in India have been found to have links with the Tablighi Jamaat congregation in Delhi.
