Over forty people, including 11 policemen, were injured in clashes between Trinamool Congress activists and police during a TC-led farmers' march to prohibitory order-bound Singur where construction work by the Tatas on a car plant entered the fifth day on Sunday.
Inspector General of Police (Law and Order) Raj Kanojia said in Kolkata that police had to charge with canes against the agitators who resorted to brickbatting against security forces at Dankuni, 8 km from Singur where the police set up a barricade to prevent the protestors from going towards Singur.
Kanojia said police also used water cannons and burst teargas shells to disperse the protestors.
"Eleven policemen were injured in the clashes, four of them had to be taken to the hospital for first aid," he said.
He said protestors armed with bamboo poles gathered at four points in the district in the afternoon to kickstart the days' agitation against alleged forcible acquisition of fertile farmland for the project.
Trinamool Congress claimed over 30 of its supporters sustained injuries in "unprovoked" police lathicharge.
Police at Singur said Naxalites had tried to set ablaze the fencing at Gopalpara village of Singur bloc but failed following police action.
At Maitipara, the agitation was led by Trinamool General secretary Mukul Roy, MP.
Trinamool sources claimed the party's youth wing chief Madan Mitra and women's front president Kakoli Ghosh Dastidar were among the injured.
