A Chinese trader was detained and sent to the Tibet Autonomous Region after she was found taking photographs of the Indian Army camps at Nathu La in Sikkim, police officials told The Hindu on the telephone from Gangtok on Wednesday.

Bichen Chomu crossed the border on Tuesday morning and started taking photographs with her mobile phone. Personnel of the Indo-Tibetan Border Police (ITBP) immediately detained her and seized the phone, said Mandeep Singh Tuli, Superintendent of Police, Sikkim East District. She was sent to the Chinese side in the afternoon according to the Standard Operating Procedure (SOP) of the ITBP, Dr. Tuli added.

Trade through Nathu La, located at an altitude of approximately 14,140 feet, resumed in July 2006 after 44 years.

Indian traders go so far as the trade mart at Renquinggang in the Tibet Autonomous Region, while Chinese traders visit Sherathang in East Sikkim.
