In 2013, the accused had sent two tins containing the solvents to Chennai which were returned citing quality concerns.
On October 1, 2016, Nandagopal sold one of the kegs to a jalebi vendor Anil Kumar.
That night, at 7 pm, the container exploded as the gas exerted excess pressure on its walls, injuring one. On the next day, the second vessel went off, injuring three more.
The police have launched a probe and are extracting details to know whether or not this was merely a mishap.
