Two people have been killed and two others, including a child, injured when a battery on-board a boat exploded in an entertainment park in east China's Jiangsu Province, officials said on Sunday.
After an initial probe, police and work safety watchdogs in Yizheng City have confirmed that Saturday's blast was caused by the boat's lead-acid battery and ruled out the possibility of sabotage, local officials said.
The accident occurred in Hongshan Sports Park of Yizheng, when four people on the boat fell into water following the blast.
All four were injured and rushed to a hospital.
Two of them died after emergency treatment failed and the two others, including one child who was slightly injured, were hospitalised, state-run Xinhua news agency reported.
Operation of the park has since been suspended for further investigation.
