A batch of students of Dr Ambedkar Law University and Dr Ambedkar Government Law College here continued their fast demanding an independent probe against Colombo for alleged war crimes.
As the anti-Sri Lanka protests by students spread to more places, the state government had yesterday instructed all arts and science colleges to remain closed till further orders.
Meanwhile, around 50 activists of pro-Tamil outfits were arrested when they blocked suburban train services at different places in the city, police said.
However, the school students were removed by police and sent back to their school, police said.
Students from some engineering colleges too joined the stir expressing solidarity with the fasting colleagues.
