Samples from the recovered material were being sent for further forensic examination since Thursday, the region's director general of police Nalin Prabhat said.

"However, unfortunately during this course (on Friday) around 11:20pm, an accidental explosion has taken place," he told reporters.

The victims included police personnel, forensic team members, two crime photographers, and other members from the local administration.

"The building of the police station has been severely damaged and the adjacent buildings have been affected," he added.

The explosion comes just days after powerful blast on Monday killed at least 12 people and wounded 30 others in the Indian capital New Delhi.
