The SFI activists went on a rampage in Rahul's office challenging the law and order system. The police failed to act and prevent the attack despite being informed by the State Intelligence Department.
The police reports clarify that the SFI members have no role in pulling down the picture of Mahatma Gandhi during the attack on Congress MP Rahul Gandhi’s constituency office at Kalpetta, Wayanad.
The decision was taken in connection with the vandalisation of Wayanad MP Rahul Gandhi's office. It was found the protest march on June 24 was held without consulting the state committee.
Rahul Gandhi reached the office along with other senior Congress leaders and took stock of the damage.
He is also expected to take part in a protest march against the move to create a 1 km wide buffer zone around forests.
Congress is planning to hold various protest programmes, including a march to the office of the Deputy Superintendent of Police, if there is any further delay in arresting the culprits.
