Tibetan activists Monday defied security and managed to stage a small protest near the Taj Palace Hotel in New Delhi where Chinese premier Li Keqiang is staying, police said.
Three Tibetan students climbed on top of a structure in a filling station near the hotel and shouted slogans for a free Tibet, an official said.
They also displayed a banner that read "Li Keqiang, Tibet will be free".
The three students were detained by police.
Several roads were blocked and Metro stations shut in view of Li's visit to New Delhi. He came Sunday and leaves Tuesday for Mumbai.
There have been no major incidents of protest by Tibetans during the visit.
