Lu Guang’s photojournalism series has exposed the sides of China that its government isn’t keen on talking about drug addicts, HIV patients, environmental problems, and so on. This time, however, the famous photographer has himself become the center of a story. His wife Xu Xiaoli claims she hasn’t heard from her husband since the 3rd of November.

On 23rd October, the photojournalist flew to Urumqi, the capital of Xinjiang region, where he had planned to attend some photography events. Later, he was to fly to Sichuan to meet his friend Mr. Chen to participate in a charity event. But Mr. Chen was unable to find or contact the photographer.

When Mr. Chen asked Guang’s wife about his whereabouts, she had nothing. Investigating the situation, Ms. Xu contacted the wife of the person who had invited her husband to Xinjiang. She was told both Mr. Lu and the host had been taken away by national security for allegedly being politically incorrect. Local officers from Zhejiang province, Mr. Lu’s hometown, later confirmed this.

“He has been lost for more than 20 days”, said his wife. “As his most direct family member, I have not received any notice of his arrest,” Ms Xu said on Twitter. “I have repeatedly contacted Xinjiang police but have been unable to get through. It is our 20th wedding anniversary [next week]. We should be celebrating it together. I can only hope for his safe return.”

According to the BBC, Xinjiang has become notorious for its tight security controls, heavy surveillance, and police presence, tackling what they describe as growing radicalism among the ethnic Uighur Muslim community. The government is sensitive to criticism and has detained reporters who were investigating negative stories about China in the past.

“The reality in China is you never know if you’re going to get into trouble because there are no written rules,” the photographer said in an interview last year.

The acclaimed best photographer in journalism won at the 2004 World Press Photo competition for his exposure of “AIDS villages”, where 678 people got infected with HIV after selling their blood. Out of 3,000 people, 678 have contracted HIV and 200 have died.

Cédric Alviani, the director of Reporters Without Borders’ East Asia bureau, called on China to disclose where Lu is and to “guarantee journalists’ freedom of movement and security, including in Xinjiang Province.” It has not answered yet.
