"A fire broke out at the vendor park of M/S Supreme Treaves, our supplier of trim parts for the Nano. The fire is under control now and no injuries were reported," a Tata Motors spokesperson said in a statement.
The company said it is in the process of ascertaining the extent of damage due to the incident.
While there is no impact on production of Tiago, the company is still assessing whether Nano manufacturing will be affected, the spokesperson added.
The plant was set up after Tata Motors was forced to withdraw the Nano project from its original site at Singur in West Bengal in October 2008 as it faced opposition from displaced farmers led by Trinamool Congress.
