KOLKATA - A Congress legislator and a Communist Party of India-Marxist (CPI-M) leader were injured and an office of the Revolutionary Socialist Party (RSP) torched at Naoda in West Bengal’s Murshidabad district Wednesday.

Police said the legislator has been admitted to the Baharampur New General hospital with a head injury. He will be transferred to a Kolkata hospital soon.

The disturbances began in the morning when Congress supporters, who had gone to meet the CPI-M gram panchayat chief of Sarbangapur Sukhdeb Mandal, got enraged and beat him up after an altercation.

CPI-M supporters allegedly retaliated a little later, as they pulled out Naoda legislator Abu Taher from his car and hit him on his head.

A profusely bleeding Taher was first admitted to a local hospital before being transferred to Baharampur.

As news of the attack on Taher spread, Congress workers blocked roads and vented their fury on the office of the RSP - a partner of the state’s ruling Left Front. The office was ransacked and the furniture damaged before Congress workers set fire to it as also some cycles outside the premises.

Tension prevailed in the area and both Congress and CPI-M have given separate calls for 12-hour shutdowns in Naoda.

The incident created a bedlam in the state assembly here as irate Congress members raised slogans inside the house before staging a noisy walk-out against the CPI-M’s “atrocities on political opponents”.
