Eleven members of an extended family were found dead in a property in Delhi.
Police say 10 of the deceased were discovered hanged from the ceiling, with a woman in her 70s found lying on the floor.
The family, originally from Rajasthan, had lived in Delhi for more than 20 years and ran two shops on the ground floor of a three-storey building where they also lived.
Police have not ruled out murder but have also released a statement saying they had found evidence of "mystical practices" by the family due to handwritten notes, which were recovered from the scene and appear to have some links to the deaths.
