The North Jakarta Intercultural School (NJIS), situated in the Kelapa Gading district of North Jakarta, became the target of a serious bomb threat on Tuesday, October 7th. This alarming menace was conveyed via a WhatsApp message, which explicitly demanded a ransom of 30,000 USD and provided a specific Bitcoin address for the payment. The sender warned of an explosive detonation if their demands were not met.
Confirming the grave incident, Kelapa Gading Police Chief, Kompol Seto Handoko Putra, announced on Wednesday, October 8th, that police were actively investigating the bomb terror information received at the NJIS Kelapa Gading campus. He further revealed a critical detail regarding the threat’s origin: 
“The threat was sent via a WhatsApp number originating from Nigeria.”
In immediate response to the serious warning, Kompol Seto Handoko Putra confirmed that his team, alongside the elite Gegana Bomb Disposal unit, conducted a comprehensive search across the entire school premises. This meticulous sweep yielded no suspicious objects, leading to the declaration that the situation was secure and conducive. Consequently, normal teaching and learning activities at the school promptly resumed, with the police chief reassuring the public, “School is still running.”
Despite the immediate “all clear,” authorities are continuing their intensive police investigation into the source of the bomb threat. As part of their efforts to unmask the perpetrator, police have engaged in coordination with various crypto exchange platforms. This extensive checking process, involving all 30 registered Crypto Exchanges in Indonesia, is still ongoing, with no definitive results yet available.
In a significant development, however, Kompol Seto reported the findings from coordination and checks with Mohammad Naufal Alvira, Vice Chairman of Crypto Asset. He stated, “The wallet address in question was not found, or it was deemed invalid. Therefore, it was not discovered or available on local crypto exchanges in Indonesia.” This crucial detail suggests that the provided Bitcoin address was either non-existent or untraceable within Indonesia’s regulated crypto ecosystem, complicating the tracking process.
2 Other Schools Also Threatened
Alarmingly, the NJIS bomb threat was not an isolated incident. On the same day, Tuesday, October 7th, two other prominent educational institutions, Mentari Intercultural School in Parigi Baru, Pondok Aren, South Tangerang (Tangsel), and Jakarta Nanyang School in BSD City, also received similar bomb threats. The pattern observed was identical: the perpetrators sent their menacing messages via WhatsApp, utilizing a phone number with the +234 country code, indicating an origin from Nigeria.
AKBP Victor Inkiriwang, the South Tangerang Police Chief, confirmed that these threats were received by the schools on Tuesday morning, highlighting a potentially coordinated nature to these criminal acts.
