The incident follows a hoax threat received by the Union Home Ministry office the previous day. The threats to educational institutions and government offices add to a string of similar incidents in Delhi-NCR. 


Earlier on Thursday, three hotels in Bengaluru, including a five-star establishment, were also targetted by bomb threats. 


The wave of such threats began on April 30 when Chacha Nehru Hospital in Delhi received a threat, followed by 150 schools on May 1. These threats were traced back to a Russia-based mailing service company. 


Subsequently, on May 12, twenty hospitals, the Indira Gandhi International Airport, and the Northern Railways' CPRO office in Delhi received bomb threats via emails originating from a Cyprus-based mailing service company. 


On May 14, seven Delhi hospitals, and Tihar Jail also received similar threats from the same source. 


The recent threat to the Home Ministry office, received via email, raised alarm as it warned of an impending explosion, claiming that a bomb had been planted with the premises.
