Who is responsible for investigating a bomb explosion that occurs in a train station?

The Homicide and Ordnance Disposal Unit is responsible for investigating a bomb explosion at a train station because this unit is specifically trained to handle incidents involving explosives. Their expertise encompasses both the investigation of potential homicide scenarios tied to the bombing and the safe disposal of ordnance, which is critical in ensuring that any residual explosives do not pose further danger to the public or investigators. This dual focus means that they are well-equipped to assess the scene of the explosion, gather evidence, and analyze the circumstances surrounding the event.

Other units, while they have important roles in their respective areas, do not possess the specific training related to explosive devices or the investigation of crimes tied to such acts. For example, the Traffic Enforcement Unit primarily deals with road traffic-related offenses and has no involvement in bomb investigations. The Fire Investigation Unit typically addresses fires and explosions that may arise from fire hazards but does not usually manage bomb-related incidents. The Special Investigations Unit handles various cases that require specialized investigation but is not specifically designated for bomb threats or explosive incidents. Thus, the Homicide and Ordnance Disposal Unit is uniquely suited for this type of investigation.
