At least 12 students of Government Law College were arrested for blocking the road and burning the effigy of former President Abdul Kalam near the collectorate on Tuesday.

The students were agitated over former President's support to Kudankulam Nuclear Power Plant project. They also raised slogans against Kalam.

"The nuclear plant is a great threat to the future of the country and its people," said Devasahayam, one of the students.

The state requires power for its development but it should not be at the cause of many lives, who would be affected by the implementation of the nuclear power plant, he said. The protest created traffic jam for nearly half-an-hour outside the collectorate. The city police arrested the students and filed a case under sections 143, 341 and 285. The students were later released on bail.
