NEW DELHI (AFP) - Indian police firing tear gas stormed a New Delhi camp Sunday to evict a mass protest against corruption by a yoga guru and thousands of followers, sparking violence that left more than 70 injured. Opposition parties and anti-graft campaigners accused the government of resorting to heavy-handed tactics to crush the peaceful demonstration, which comes after a damaging series of corruption scandals. Police used batons and dragged away demonstrators in the early-hours crackdown on a vast tent in the centre of the capital where Swami Baba Ramdev, a television yoga star, had begun a hunger strike on Saturday, witnesses said. "We had given permission for only 5,000 people to attend his yoga camp but 50,000 turned up. We had not given any permission for a public agitation," Delhi police spokesman Rajan Bhagat told AFP. Ramdev later said his fast would continue and he vowed to intensify his campaign, which has the backing of the main opposition party and several far-right Hindu nationalist groups.
