In Assam, people who are unable to undergo home quarantine in their residences can stay at designated lodges and hotels and complete their isolation period.

The man was a goldsmith by profession and his wife and two children reside in West Bengal. His other relatives stay in Dhubri town, a police officer said.
His body has been sent to the Dhubri Civil Hospital for post-mortem examination and an investigation into the case is underway, he said. ESB ACD ACD
