Rahul Gandhi, leader of India's opposition party Congress, was detained today after he led a protest and sat on a road in the heart of India's capital New Delhi while his mother Sonia Gandhi was being questioned by the Enforcement Directorate, reports NDTV.

The Congress leader protested about a number of concerns, from price rise and the GST to the targeting of opposition leaders by investigation agencies, while sitting on Rajpath, the tight security boulevard close to parliament and major government offices.

A policeman lifted the Congress MP and placed him in the bus with other MPs who were previously held following a standoff that lasted for around 30 minutes, the NDTV reports adds.

"India is a police state, (Prime Minister Narendra) Modi is a king," Rahul Gandhi said before his detention.
