A teenaged boy was injured in an explosion in West Bengal's North 24 Parganas district on Sunday.
The central trade unions’ 48-hour nationwide strike remained largely ineffective across West Bengal on its second day on Wednesday barring a few sporadic incidents of vandalism.
Train services were briefly affected on the Sealdah-Lakshmikantapur Namkhana and Diamond Harbour sections of Eastern Railway as strike supporters threw banana leaves on overhead wires.
A few trains, including the Howrah-Puri Satabdi Express, however, had to be cancelled, an official said.
Train services were also halted on the Sealdah-Habra line after a number of crude bombs were found along the railway track near North 24 Pargana district’s Habra area.
The protestors allegedly ransacked a public bus in Cooch Behar’s Dinhata area.
Another bus was vandalised in Howrah district’s Dasnagar where two schoolchildren sustained minor injuries.
On Tuesday, few Left activists, including CPI-M leader Sujan Chakraborty, were detained while picketing in south Kolkata’s Jadavpur. He was later released.
Left activists and members of the trade unions staged a rally in north Kolkata’s Shyambazar.
Another group of protesters clashed with the police near Howrah’s Bally.
