Tension prevailed in trouble-torn Nandigram, which witnessed some incidents of violence on Tuesday.
"There were some incidents, but it was controlled. The Central forces sought by the state administration are yet to arrive. We had written to the Centre yesterday seeking forces," Home Secretary P R Roy told reporters in Kolkata.
Nandigram has witnessed frequent clashes between ruling Communist Party of India-Marxist and opposition Trinamool Congress.
Chief Minister Buddhadeb Bhattacharya had on Monday briefed Union Home Minister Shivraj Patil on the situation in Nandigram and sought Central reserve police.
To a question, the home secretary said the state administration has taken no decision to seal Nandigram's border with Khejuri.
Trinamool Congress chief Mamata Banerjee had on Monday demanded that Nandigram's border with Khejuri be sealed to stop continuing violence.
Asked whether the state government was for a political solution to the problem in Nandigram, Roy said the chief minister himself had stated that he wanted a political solution.
Meanwhile, Trinamool Congress general secretary Partha Chatterjee, who visited Nandigram on Tuesday, said he would try to visit the areas affected by violence in the past few days.
