More than nine lakh bales of cotton and yarn worth crores of rupees were burnt to ashes when a fire swept through a private spinning mill in the district in the wee hours on Sunday.

The fire broke out at the mill in Suriampalayam in Gobichettipalayam taluka, 50 km from here, past midnight on Saturday and started spreading to all areas, including the godown, where huge quantities of cotton and yarn were stocked, police said.

Since workers were not present at that time, casualties were low, they said.

More than nine lakh bales of cotton and yarn kept in the mill and godown were gutted in the fire, they said.

Fire and Rescue Service personnel with fire tenders rushed to the spot from nearby towns and doused the blaze after more than ten hours of battle, they said.

The cause of the fire was immediately not known.
