Indian opposition leader Rahul Gandhi and his sister Priyanka were detained by police during the Congress party's protest against inflation and rising unemployment in Delhi on Friday. Rahul, Priyanka and other senior leaders of the party were bundled into police jeeps and taken to Police Lines at Kingsway Camp as soon as they embarked on the protest near the Congress headquarters in the heart of the national capital. "We're witnessing the death of democracy. What India has built brick by brick, starting almost a century ago, is being destroyed in front of your eyes. Anybody who stands against this idea of onset of dictatorship is viciously attacked, jailed, arrested and beaten up," Rahul told the media.

A senior police officer told the local media that they were compelled to crack down on the protesters in the wake of the imposition of prohibitory orders by the authorities. "We have also not given them permission to hold any protest in Delhi," he said. Rahul, son of Sonia and former Prime Minister Rajiv Gandhi, is seen by many as a future prime minister of India. Apart from his father, his grandmother Indira Gandhi and great grandfather Jawaharlal Nehru have all served as prime ministers of India.
