Two Tibetan youth staged a protest in front of the Chinese embassy in New Delhi on Monday, demanding the release of Tibetan monk Tenzin Delek Rinponche's body.
One of them climbed a pole to put up a banner with the monk's picture to express his views and anger.
The protester was made to come down by the police who arrested him and took him away.
Rinpoche, 65, was 13 years into a life sentence for terrorism and separatism, imposed following a trial which observers said was deeply flawed, when authorities announced news of his death at the weekend.
Earlier, Tibetans in-exile in New Delhi held a massive protest march against China on the fifth day after Tenzin Delek Rinpoche's death in prison.
Rights groups say the circumstances of his death were unclear and the family said Delek was cremated against their wishes.
But Xinhua news agency said authorities had been quick to treat Delek after finding him "suffering respiratory failure", though he subsequently died of a heart attack.
"The monk's right to health care has been guaranteed since his imprisonment," Xinhua said, adding that Delek had sometimes refused treatment for an unspecified "disease".
Delek was cremated on Thursday before Tibetan burial rights could be carried out, according to Students for a Free Tibet (STF).
And on Friday Delek's sister and her daughter were taken away by police in the southwestern city of Chengdu, SFT said, citing Geshe Nyima, Delek's student and cousin.
Several protests in Delek's home town and in Chengdu, where he was jailed, have taken place since his death was announced, according to the US-based International Campaign for Tibet and other rights groups.
Police opened fire when around 1,000 people gathered near government offices in Nyagchuka county to protest at the death, injuring about 20 people, the British-based Free Tibet group said.
