Nandigram has witnessed continuing violence since January when the deaths of the six people forced the chief minister to concede that no land would be taken forcefully for any project.
On July 31 last year, the state government signed an agreement with the Salim Group to implement various developmental projects, including a mega chemical industrial estate, to be spread over 10,000 acres in a 50:50 joint venture.
