Police in India arrested 47 Tibetan protesters Wednesday during a demonstration outside the Chinese embassy in New Delhi.
Nearly 100 Tibetan exiles had gathered outside the building to mark the anniversary of a failed uprising in 1959. Many members of the exile community, including the Dalai Lama, have lived in India ever since.
Witnesses said the demonstrators wore yellow T-shirts saying "Free Tibet" and chanted "We want freedom" in defiance of regulations barring protests around the embassy.
Police dragged dozens of the demonstrators into a bus and detained them for questioning. The Associated Press quoted police as saying those detained would likely be released later in the day.
India provides a refuge to the Tibetan exiles but tries to avoid high-profile events that would anger neighboring China, which is highly sensitive to Tibet.
The Dalai Lama is scheduled to mark the anniversary of the uprising on Thursday with a speech at Dharamsala, the headquarters of his government in exile.
