The constable identified as Subash Tomar was admitted to RML hospital and reported to be in a critical condition, Delhi Police Commissioner Neeraj Kumar said. Around 100 protesters and some media personnel were also injured in the violence, police said.
Police also resorted to lathicharge and lobbed around 150 teargas shells to disperse the protesters.
Special Commissioner of Police (Law and Order) Dharmendra Kumar blamed “hooligans” for the violence during protests against the gangrape of 23- year-old girl in a moving bus last Sunday night and said unruly elements have “hijacked” peaceful demonstrations.
