Duration of the ban orders under section 144 CrPC at Singur, earlier extended for 20 days, would be further in force till January 28 midnight after assessing the situation there, the official said.
He said there were reports that some groups, opposed to farmland acquisition for the Tata project, might instigate trouble if the orders were lifted. "In fact there had been some attempts to weaken the poles of the fenced area and damage the barbed wire," he said.
The Krishi Jami Bachao Committee -- comprising Trinamool Congress, PDS and some Naxalite outfits -- have already stated they would continue to oppose the administration's land acquisition plans. The SUCI, APDR is also waging a movement against farmland acquisition.
