A part of Central Delhi has remained tense after Sunday's clash between two groups and vandalism at a temple. Three people, including a minor, have been arrested since last night over the violence in Old Delhi's Hauz Qazi, which started as an altercation over parking space. Over 1000 security personnel - police and Central Reserve Police Forces -- have been deployed in the area. Shops have been shut since Sunday and the locals have held a peace march.
