The party claimed that one of its supporters had died and five others were injured in clashes with the police during a 12-hour shutdown Thursday in the violence-affected Mongolkote block in Burdwan district.
However, police and family members of the victim said the Congress supporter died of cardiac arrest.
Eight Congress legislators of West Bengal were injured Wednesday when they were allegedly attacked by armed Communist Party of India-Marxist (CPI-M) cadres at Mongolkote.
The attack took place when a 14-member delegation led by Congress Legislative Party (CLP) chief Manas Bhuinya had gone to Dhanyarukhi village in Burdwan district Wednesday to distribute relief material among party supporters whose houses were burnt after the murder of CPI-M district committee member Falguni Mukherjee.
Seven journalists who had gone to the spot to cover the delegation's visit were also injured as they were allegedly beaten up by CPI-M cadres and hit by bricks. Five journalists had to be taken to hospital.
The area has been restive since Mukherjee was shot dead at point blank range June 16.
