In a statement announced Tuesday, the Kolkata Police said that more than 20 schools across the city have been threatened with bombs, which have been later revealed as hoaxes. According to the sender, bombs had been placed in numerous classrooms across a variety of schools in the city, and the bombs would explode in the morning hours following the placement. 

After receiving a hoax bomb threat mail on Monday, Kolkata Police took the initiative to spread an online message on Tuesday to reassure all parents that they would be there to ensure their children's safety and security, clarifying that it was a hoax mail and that they would be on hand to help. It has been revealed that police have traced the IP address to the Netherlands where the threat mail which was sent to 200-odd schools in the city, suburbs, and Siliguri, was sent from.

On the intervening night between Sunday and Monday (April 8, 2024), a user known as "doll" sent an email at 12.28 am on Monday with the email address 'happyhotdog101' threatening to have bombs placed in schools. The user threatened to make it happen with the help of the U.S. Government.   An email screenshot has been shared by over 90 schools and the screenshots have been shared on more than a dozen websites. 

The message itself has not been shared yet, but the fact that it has gone viral has contributed to its success. The sender, it is thought, had threatened the students that bombs would be detonated when they arrived at school that morning and that this was the reason for the mail. 

There had been no official announcement regarding this case from either the Calcutta Police or the West Bengal Police until late that evening. There is also the possibility that none of the schools in either of the cities will publicize the threat. The email reads, “This is a message for everyone. There are bombs planted inside "of the" classrooms. The bombs are set to go off tomorrow morning when there are kids inside "of the" schools. Our mission is to leave as many as people in a pool of blood." 

his attack was caused by 2 terrorists named Ching and Doll." According to the Latvian police, the email had been generated by an account linked to an email service provider founded in 2018 and set up its operations in 2022, but it was conceived in 2018 and started operating in 2022. 

Around 68 educational institutions in Bengaluru received a threat email last January, which came from one of the email addresses that were created by the same company that provides email services to these institutions. Initially, Bengaluru police speculated that the email was coming from either the Czech Republic or Slovakia, but they have since removed that suspicion. 

In the course of the investigation, it was found that the encryption service provider in question was the same as the one used in the Calcutta school case, though the location was in Cyprus instead of India. It was reported that the email sender said that he used a Switzerland-based Virtual Private Network, which is also well-known for the security and privacy of end-to-end encryption and focus on privacy, to send the email according to reports from the Bengaluru Police. 

There is an announcement that, in June 2022, the Narendra Modi government will ask all VPN operators to store for five years data related to its subscribers, such as names, email addresses, contact numbers, and IP addresses to tighten cybersecurity rules. Also, the Indian government requested the use of the data at its discretion as and when it deemed necessary. As a result of the order, most VPN companies have declared themselves uncooperative and have removed their servers from India as a result.

The Calcutta Police and the Bengal Police are yet to discover whether the email service provider has been contacted by either the Calcutta Police or the Bengal Police to review Monday's threat emails as yet. Amidst a flurry of concerning emails inundating over 90 schools across Bengal, authorities promptly alerted law enforcement, triggering a swift response from the cyber crime cell. Their immediate objective: pinpoint the sender's identity through meticulous analysis of the email's IP address. Offering insights into the unfolding situation, a senior police official asserted that the dissemination of such emails was a deliberate ploy aimed at stoking tensions in the lead-up to the elections, underscoring the malicious intent behind the communication. 

In a bid to assuage public concerns, the city police took to social media to affirm that the purported threats were indeed unfounded, branding them as mere 'hoaxes' intended to sow panic and unrest. Further action was swiftly undertaken by authorities, with the registration of a formal case against the individual responsible for the email transmission, signalling the commencement of a thorough investigation into the matter. 

This incident is but the latest in a string of similar occurrences, with the Delhi Police, just last March, apprehending a 29-year-old Bangladeshi national residing in Kolkata for orchestrating a hoax bomb threat targeting a SpiceJet flight en route from Delhi to Kolkata. Delving into the motives behind the elaborate ruse, law enforcement disclosed that the perpetrator, upon interrogation, confessed to concocting the threat in a bid to derail the flight and thus prevent the imminent arrival of his brother-in-law in Kolkata. This calculated manoeuvre, as elucidated by police officials, stemmed from the individual's desire to conceal a web of deceit, as he had falsely claimed to be pursuing a PhD in the United States—a fabrication that facilitated his marriage to his spouse.
