A Tibet official said 100 people had given themselves up to police for taking part in riots that rocked the regional capital, Lhasa, state television reported.
The official said the people who surrendered to authorities had been "participants, and some were directly involved in beating, smashing, looting and arson" last Friday, Chinese television reported.
"Some handed over money they'd stolen," the official added.
The report was the first word of people surrendering to authorities after they laid down a Monday midnight deadline urging rioters to hand themselves in or face tougher punishment if caught. The official also said that arrest warrants had been issued for others.
