A Delhi Police personnel who suffered head injury during clashes with protesters at the Cockroach Janta Party's (CJP) 'Sansad Chalo' protest claimed that miscreants may have fuelled the agitation. "We asked the students not to march towards Parliament...but they pelted stones at us," Head Constable Naveen Ola said. "The stones looked similar to those found on railway tracks," he added.
