Tibetan refugees continued to protest Friday Chinese President Xi Jinping's visit here.
Protesters held Tibetan flags and shouted slogans of freedom, and tried to march towards the Taj Palace Hotel, where the Chinese president is staying.
However, police stopped them on way and detained 20 demonstrators, including three women, in south Delhi.
Tibetans were detained Thursday as well after they staged a demonstration at Hyderabad House in central Delhi where Xi held talks with Prime Minister Narendra Modi.
They had also staged a demonstration at Majnu-ka-Tilla, a Tibetan colony in the national capital.
To block any further protest against Xi, Delhi Police have deployed personnel in many areas, especially near Majnu-ka-Tilla.
A police officer said that the security personnel will be deployed till Friday noon when the Chinese president is scheduled to fly back to his country.
Xi is on a three-day official visit to India and will depart later in the day.
