Kalsang Yarphel, a popular Tibetan singer from Machu County in his early 40s, has been released from prison after a four year sentence. Photos circulated on social media showed fellow Tibetans welcoming him home with traditional scarves. There are no details about his health. Yarphel was arrested in 2013 for organising a music concert promoting unity, as well as urging Tibetans to speak and write in their own language.
