* Aminbuhe arrested on Oct. 11, detained in Rizhao - SouthGobi
* Board forms special panel to probe charges against CEO - firm (Adds no comment by person at Rizhao detention center)
Nov 17 (Reuters) - Coal miner SouthGobi Resources Ltd said on Friday Chairman and Chief Executive Officer Aminbuhe was arrested on Oct. 11 and detained at the Rizhao City Detention Center in China as a suspect in a fraudulent loan case.
SouthGobi's board has formed a special committee to investigate the charges against Aminbuhe, it said.
Earlier this week, the company said Aminbuhe was on leave and appointed Bing Wang as interim CEO.
A person who answered the phone at the Rizhao detention center when Reuters called on Saturday would not comment on Aminbuhe's detention.
Aminbuhe joined SouthGobi as non-executive director in August 2015 and became the CEO a month later.
Before joining SouthGobi, Aminbuhe was a director at National United Resources Holding Ltd.
