A charity worker who was released from Mandalay’s Obo Prison under a junta amnesty earlier this year has been arrested again, according to sources close to her family.

Relatives of Nwe Nwe Win, the chair of the Shwe Mahar Nwe Social Welfare group, said they lost contact with her after she left her home in Mandalay’s Chanmyathazi Township on Wednesday afternoon to donate blood at a local hospital.

“After she left for the hospital, her phone went dead. We didn’t know she had been arrested until we saw the post on Han Nyein Oo’s Telegram channel,” said the family friend, who spoke to Myanmar Now on condition of anonymity.

Han Nyein Oo is the name of a pro-junta social media account that had earlier made calls for Nwe Nwe Win’s arrest. Late Wednesday, it posted photos of her blindfolded and seated in the back of a police vehicle after she was arrested for “engaging in political activities under the guise of social work.”

In a previous post, the channel showed a photo of a woman that it claimed to be Nwe Nwe Win holding up a sheet of white paper with the words “35th anniversary of the 8-8-88 uprising” written on it. Tuesday, August 8, was the anniversary of the 1988 pro-democracy protest movement.

“They posted that photo just hours before she was arrested, but that wasn’t her in the photo,” said the family friend. “Since her release, she hasn’t been politically active at all. She has only been doing charity work.”

Another friend agreed that the woman in the photo, whose face was blurred, was not Nwe Nwe Win.

“They have entirely different hairstyles. And [Nwe Nwe Win] wouldn’t post such a picture on her Facebook,” said the friend, who also did not want to be named.

“Somebody framed her,” she added.

Nwe Nwe Win’s friends and family also expressed concern about her health, as she has been receiving treatment for a number of medical conditions since her release from prison in early May.

Nwe Nwe Win was arrested during a raid on her group’s office in Mandalay’s Aungmyay Thazan Township on November 15, 2021. She was later handed a three-year prison sentence on charges of incitement.

Hundreds of political prisoners, including doctors, lawyers, teachers, social welfare activists, and monks, are currently being held at Obo Prison and in the notorious Mandalay Palace interrogation centre, where many have died in regime custody.

Pro-junta Telegram channels have increasingly been used to target activists opposed to the regime that seized power in February 2021.

According to the Assistance Association for Political Prisoners, at least 24,238 people have been arrested since the coup, of whom 19,733 are still in detention.
