The driver of a private bus was arrested on Wednesday for rash driving in connection with the death of the leader of CPI-M's student wing in Kolkata.
According to the police, 22-year-old Sudipta Gupta had sustained injuries after he fell from the bus ferrying SFI supporters, who were arrested during a protest against postponement of college elections in the state.
However, the CPI-M had alleged that Gupta succumbed to his injuries suffered in a lathicharge by the police during the protest.
Further investigation into the case is being conducted with the arrest of the bus driver, a senior police official said.
The police claimed that SFI supporters had turned violent and threw rotten tomatoes and eggs at the policemen deployed in their protest venue.
Meanwhile, an SFI leader told reporters on Wednesday that inspite of an advance notice by the student body, there was no adequate police deployment at the venue of their protest where over 6,000 students, including women supporters, had assembled.
In protest against the incident, the SFI has called for a 12-hour 'bandh' in some area of south Kolkata on Thursday.
