The North Block is home to the home ministry office. Authorities thought the bomb threat that sparked concerns there on Wednesday was a hoax as nothing odd was found. According to a Delhi Fire Services (DFS) official, the threat was sent by email to a top ministry staffer at around 3:30 pm. The email claimed that the "building will explode as a bomb is planted," according to a police officer. The IP address and other contact details are being looked into.

A PTI report stated that an unidentified officer, who wished to remain unknown, stated that the email was sent from a Gmail account and that the sender may have used a VPN to conceal their IP address. As the Delhi Police Special Cell has already started looking into the incident, the officer anticipates that they would file a complaint. For the search at the North Block, military personnel, police officers, firefighters, dog teams, bomb disposal and detection units were sent in.
