With one more person succumbing to injuries at the government hospital in Sivakasi on Thursday, the toll in the explosion at a cracker manufacturing unit has gone up to eight, police said.

One Thangapandi died this afternoon without responding to medical treatment at hospital following injuries, they said.

Three persons were undergoing treatment at the hospital and their condition was out of danger, they said.

Three persons were killed and eight injured in the incident on April 28. Four more persons succumbed to injuries in the subsequent days.

The victims were workers of the unit at Narayanapuram village, four km from Sivakasi, the country’s fireworks hub, and they were engaged in making crackers when the explosion occurred.

The owner of the unit and its manager are absconding, police said, adding, a hunt is on to nab them.

The explosion apparently occurred due to friction among the chemicals.
