Three young men jumped onto the floor of assembly around 10:30 in the morning, triggering chaos and a rough chase from marshals.
Chief minister Omar Abdullah was present when the incident occurred. He tried to direct the marshals not to beat the youth but the CM's intervention failed to pacify security personnel.
The youth claimed that they were protesting against the non-implementation of employment scheme in the state.
The government is denying any breach of security as the boys made entry on valid passes.
