Civil Service aspirants today tried to march towards Parliament and were taken into preventive custody by police as they stepped up their protest against the CSAT exam.

The protesters were stopped by police outside Central Secretariat metro station from where around 300 of them were taken to Parliament Street police station.

Two Metro Stations -- Central Secretariat and Udyog Bhavan -- were shut at 12:45 pm in order to prevent the protesters from reaching anywhere near Parliament House. The two stations were later opened at 3:00 pm.

"We did not lathicharge any protesters and used minimal force. We had to physically evict them as they lay down on the road. Some of them tried to flee but were caught and detained at Parliament Street police station... 300 protesters, including six girls, were detained," said Additional Commissioner of Police (New Delhi), SBS Tyagi.
