Trinamool Congress workers on Thursday burnt an effigy of Tata group chief Ratan Tata and shouted slogans against him and West Bengal Chief Minister Buddhadeb Bhattacharjee during a protest at the Tata Centre in Kolkata over the alleged "grabbing" of land from farmers at Singur.
Youth under the banner of Chhatra-Chhatri Samsad (Group of Students) also took out a procession from College Square in central Kolkata to Hazra in the southern part of the city on the same issue.
Police said 10 Trinamool workers were detained for the protest at the Tata Centre. The protest disrupted traffic for about 30 minutes in the area.
The Trinamool Congress has been spearheading a campaign to oppose the acquisition of land at Singur for a Tata Motors' small car plant.
