Kolkata: BJP MP Arjun Singh suffered head injuries on Sunday when police allegedly indulged in baton charge at Kankinara in West Bengal's North 24 Parganas district to lift a road blockade by a group of persons.

Singh claimed Barrackpore police commissioner Manoj Verma struck him, causing a gash on his head. The MP, wearing a blood-soaked shirt and a bandage on head, said that Verma led a police contingent which attacked a "peaceful" protest by the BJP over the capture of its party office at Shyamnagar.

A senior police officer, however, claimed that stones were being hurled during a clash between two groups at Kankinara and Singh suffered injuries in the melee.

Local sources said that a mob that had blocked a road started pelting stones at the police officers, as soon as they arrived at the spot.
