The mishap struck Rukuni Sahu and her granddaughter Laxmi at Singipur yesterday, police said.
While Rukuni died on the spot, the child succumbed to injuries at MKCG Medical College Hospital here, said Inspector In-Charge of Patapur police station A K Barik.
There is a tradition here to throw nuts to the deity while pulling the chariot. Even as the devotees were jostling to have a clear glimpse of the Lord, the duo fell on the ground before coming under the wooden wheels of the chariot, Barik said.
Pulling of the chariot was stalled following the incident and resumed today after performance of rituals, sources said.
