As the basement is still flooded, forensic experts could not go inside to collect evidence to ascertain the cause of the fire and what materials were stored there, police sources said.
The experts are expected to visit the hospital once again on Monday to carry out their investigations, the sources said. The basement was still under a few feet of water and until it was drained out, investigation and collection of samples would not be possible.
The basement was flooded by the fire brigade personnel for cooling of the overheated basement and the walls and to ensure that no new fire started from any burning ember. Six directors of AMRI Hospital have been arrested and sent to police custody for ten days after they were produced before a city court yesterday.
