Police and Fire Service personnel rushed to the scene and cordoned off the area following reports of the suspicious object.
According to police and local sources, several pedestrians spotted the object while crossing the overpass and alerted police, suspecting it to be a bomb because of the wires attached to both ends.
Jamalpur Sadar Police Station Officer-in-Charge Nazmus Sakib said police and Fire Service personnel were at the scene to secure the area.
"Whether the object is actually a bomb has yet to be confirmed. Efforts are underway to recover it," he said.
