The Election Commission has sought a report in the incident.

As polling for the fourth phase of the West Bengal elections began at 7 today, tension gripped polling booth number 285 in Sitalkuchi of Cooch Behar as bombs were hurled. Some groups allegedly opened fire when the police recovered several crude bombs from the area. The police had to resort to lathicharge to defuse tensions.
