The treasurer of the Chorbagan Durga Puja was arrested for allegedly misleading revellers by announcing that a section of the pandal was collapsing, which appeared to have triggered panic among them and led to the stampede that claimed the lives of 19 people last week, police said on Friday.

Sanjib Raha, alias Sentu, was initially detained from a hideout in Nadia district on Thursday and later arrested, a senior officer said.
