"The Modi government has put a stop to these activities. The protests we are seeing now is politically motivate and the fee hike issue is merely an excuse," he said.
Singh said one group of students is behind the agitation as they can no longer do whatever they wish as they used to do earlier.
"Tukde-tukde gang" is a term the BJP uses against those it accuses of encouraging anti-national sentiments.
Singh spoke strongly against the defacement of a Swami Vivekananda statue on the JNU campus and said it showed the real intentions of the protestors.
The Delhi Police lodged two FIRs on Tuesday in connection with the protest by Jawaharlal Nehru University (JNU) students over the hostel fee hike.
Hundreds of JNU students rocked the national capital on Monday, bringing several parts of the city to a halt. The students took out a protest march opposing the hike.
