A case under section 436 of IPC (mischief caused by fire or explosive substance with intent to destroy house) has been registered against unnamed persons in connection with the incident, a senior police official said.
The cause of the fire is yet to be ascertained. Delhi Police will conduct a forensic examination of the building and collect samples for forensic tests once the fire department declares the building safe for the exercise, the official said.
Nearly four-decade-old National Museum of Natural History, housing rare specimens including a 160-million-year old fossil bone of the Indian Sauropod Dinosaur, in the heart of the capital was ravaged in a massive blaze.
The fire started on the top floor of the six-storey FICCI building which housed the museum in Mandi House area of Central Delhi at around 1.45 AM and rapidly spread to all other floors except the ground floor.
