Pasang Wangchuk, 37, also known as Ngodru, a businessman and father of three, who was detained last month in China’s Sichuan province for launching a solitary protest has been freed after being interrogated over the slogans he wrote on his protest banner. It is not known whether he was beaten or tortured—a punishment most detained Tibetan protesters say they undergo, and it is not known why he was freed.
