A high-profile entrepreneur who founded one of China's largest multinational private training study companies is now under police investigation for allegedly raping one of his interns and sexually harassing several other female staff members.

Song Shanmu, 46, the president of the Sunmoon Lifelong Education Group, is now at a police station for investigation in Shenzhen City in Guangdong Province, the Southern Metropolis Daily reported yesterday.

He was summoned immediately back to the city from his study in Beijing after 22-year-old Luo Yun called the police saying she was raped on May 3.

Song allegedly deceived her into going to his apartment in a remote mountain area to do some cleaning work. After they arrived there, he threatened to kill her and then took pictures of her naked and raped her, she said.

Luo was a junior student in east China's Anhui Province and began teaching English at the company last year. She applied for a resignation but was turned down by Song, who kept arguing with her on their way to his apartment.

Police have found two bloody towels and one massage stick in the room at the apartment in Luohu District.

Song often seduced or forced female staff members to take porn pictures and then threatened them to have sex, said a staff member who claimed to be working at a branch of the company.

A post at Sina.com in 2008 accused Song of frequent rapes and collecting thousands of porn pictures of his female employees.
