A person died and six others, including a forest official, suffered injuries in three different accidents in Alipurduar district since Friday night.

Low visibility due to dense fog seems to be the reason behind the accidents, said police officers.

Locals rescued Rai and rushed her to Siliguri where she is under treatment at a nursing home.
