Balasore, Odisha - The Central Bureau of Investigation (CBI) on Tuesday took three people accused in the Balasore triple-train crash into its custody for four days after they were produced in a local court.

The CBI had sought a five-day remand for senior section engineer (signal) Arun Kumar Mahanta, senior section engineer (signal) Mohammed Amir Khan, and technician Pappu Kumar, but the court granted only four days.

Mahanta has applied for bail, while the other two have filed vakalatnama, a document that gives their lawyers the power to represent them in court.

The CBI arrested the three accused on July 7 under sections 304 (culpable homicide not amounting to murder) and 201 (destruction of evidence) of the Indian Penal Code in connection with the triple-train accident that took place near Bahanaga Bazar station in Odisha's Balasore district on June 2, killing 293 people.

The CBI had previously taken the trio into its custody for five days.
