The eight-member herd destroyed rice stored for children's midday meal scheme at Kamarbadi Sisu Siksha Kendra after smashing open doors last night, a forest official said.
It also gobbled rice stored in the courtyard of at least 40 houses and damaged crops in paddy field.
The herd further damaged rare saplings in Amlachoti Herbal Garden before being chased by villagers and wildlife squad, the official said.
The pachyderms, which had strayed from Dalma forest, were still roaming in the area, causing panic among the villagers.
