While raising slogans against Pratap Simha and the BJP, the Congress workers alleged that he had incited the accused to carry out the security breach inside Parliament. However, the police swung into action and took protestors into custody. Meanwhile, former MLA Yathindra Siddaramaiah, son of Chief Minister Siddaramaiah, demanded that MP Pratap Simha must face investigation and till then he should be suspended. 'We issue passes after proper inquiry and background checks. MP Pratap Simha should be directly accountable for the incident.
