Four metro stations in the heart of Delhi have been closed "indefinitely", the Delhi Police said, as hundreds of students said they want to protest in front of the Prime Minister's residence on Race Course Road.
The stations that have been shut down are Patel Chowk, Central Secretariat, Race Course Road and Udyog Bhawan.
More than 3,000 students are currently holding a demonstration at Civil Lines in north Delhi against the change in pattern of the Civil Services exams - which makes CSAT (Civil Services Aptitude Test) compulsory for those who want to become officers in the Indian Administrative Service (IAS), Indian Police Service (IPS) and other allied services.
Over 100 students have been detained from Tughlaq Road and Aurangzeb Road in central Delhi when they were protesting near the offices of the Union Public Service Commission (UPSC), the body that conducts these tests.
