Thiruvananthapuram: The march organised by Kerala Students Union (KSU) demanding an independent investigation into the mark tampering scandal in the University of Kerala and a CBI probe into the Walayar siblings’ mysterious death turned Kerala's capital into a battlefield on November 19.

During the march, protesters tried to break the barricades while the police used water cannons and later lathi-charged them. Soon police baton charged at the activists injuring several including Shafi Parambil MLA and KSU state president KM Abhijith.

The MLA suffered a head injury in the baton charge as he was visibly bleeding. Protesting the police assault on the activists, KSU has called for a state-wide education bandh on Wednesday (November 20).

Meanwhile, the opposition boycotted the Assembly protesting the delay in medical treatment given to the injured MLA. Shafi and Abhijith, along with KSU workers, courted arrest and were later shifted from the protest venue.  The injured protesters were then shifted to Medical College Hospital for treatment.
