2004 Dimapur Bomb Blast: How the Mystery of a Case Police Deemed 'Cold' Unraveled Behind Prison Walls?

It was October 2, 2004. On this day, the Dimapur railway station in Nagaland was bustling as usual. However, at around 9:30 a.m., a powerful bomb blast suddenly shook the entire area. A large part of the ticket counter and platform was destroyed. People were crying for help as many had been seriously injured. Just a minute later, a second blast occurred at the nearby Hong Kong Market. Nearly 30 innocent civilians were killed in the twin blasts, while around 100 people were injured. The incident shook not only Nagaland but the entire country. But who had plotted the attack, and what exactly was the motive behind it? The answers were given by Mangal Mahato, a man with no link to the blast incident, but who gave an extremely important lead in the case. 

Initially, to uncover the truth, the state government launched two investigations within hours. However, no concrete evidence emerged, and the case was eventually closed as a “cold case.” Then, a crucial lead in the case eventually emerged from a completely unexpected place. On July 24, 2010, Dimapur East Police arrested Abu Syed in Lakhimpur, Assam, in connection with a separate criminal case. During the investigation, police also questioned him about the long-unsolved 2004 Dimapur bomb blasts. Syed’s questioning led investigators to a man named Mangal Mahato, whom he frequently met at liquor joints in Dimapur. This is where the entire case came together.

Mahato had earlier been arrested in an auto-rickshaw theft case and had spent about four months in Central Jail, Chümoukedima. But his time in prison would later become significant for another reason. During this period, Mahato was housed near Hukoom Ali and several other inmates. All of them had been imprisoned in 2005 for a separate crime. Mahato gradually learned that these were the same men who were connected to the 2004 Dimapur bomb blast case.

With six years having passed, the men apparently believed that the case had been forgotten. As a result, they began speaking openly about the attack inside the prison. Mahato quietly listened to their conversations. From what they said, he learned that the men were involved in planting the bombs at Dimapur Railway Station and Hong Kong Market. He also heard them arguing over a payment of ₹10 lakh that had been promised for carrying out the operation. At the time, the information Mahato overheard may have seemed like an ordinary prison conversation, but it would later prove significant. It provided investigators with a crucial lead in a case that had remained unsolved for six years.

When Mahato was taken into custody for questioning, he told the police everything he had heard in prison. Based on this information, the then Officer-in-Charge of Dimapur East Police Station reopened the investigation into the case, which had remained closed for six years, on August 3 and September 6, 2010. The old files and previous leads were reviewed. Subsequently, on September 20, a joint team comprising the Assam Rifles, SIB, CRPF, Special Branch and Dimapur Police began further action. Several suspects, including Abdul Kalam, Babul Hussain, Haizul Ali and Shajan Ali, who were in prison, were questioned. During the investigation, Babul Hussain allegedly confessed to planting the bomb at Hong Kong Market on the instructions of Hukoom Ali, with the help of Panas Ali, the late Nazim Uddin, Noor Jamal and Haizul Ali.

The investigation also focused on determining the motive behind the attack. According to then Superintendent of Police Janardan Singh, the possible motive was to disrupt the peace process between the central government and Naga insurgent groups, which had been underway since 1997. In 2013, a chargesheet was filed against nine of the ten accused. Meanwhile, Nazim Uddin died by suicide while in police custody on September 9, 2010, while Hukoom Ali, the leader of the group that planted the bomb at the station, died of natural causes in prison in 2014.

Thus, the information provided by Mangal Mahato gave a new direction to the Dimapur bomb blast case, which had remained in the dark for six years, and brought the investigation back to life. The case showed that a decisive clue in solving a crime is not always found at the crime scene. Sometimes, the most important secret of a crime can remain hidden in the most unexpected of places.
