Delhi Police launched a massive protest outside their headquarters in the national capital today, agitating against the fallout of violent clashes between cops and lawyers that broke out on Saturday at the city's Tis Hazari court complex. At least 28 people, including both policemen and advocates, were injured and 20 vehicles were vandalised in Saturday's clash. That attack was followed by another violent confrontation - this time outside the Saket District Court - between a single policeman and a group of lawyers.
