Taking a swipe at the BJP, Congress MP Karti Chidambaram on Monday expressed surprise that the ruling party had "only placed barricades and police" leading to the Congress office ahead of Rahul Gandhi's appearance before the ED, while the bulldozers were "missing". Karti Chidambaram said the bulldozers may have been "requisitioned to demolish the lives and houses" of citizens belonging to the minority faith. Ahead of the proposed march by the Congress leaders, the Delhi Police on Monday imposed section 144 CrPC in the area around party headquarters at Akbar Road here asking them not to violate the law.
