A man who had returned to Shenzhen after studying in Japan is in some serious hot water after keeping a girl as his sex slave for a week.

The man met the girl over the internet and locked her in a dog cage in his home in Longgang District until she escaped on February 28, TVS reports.

Miss Han, 20, ran through Vanke No. 5 Garden in Bantian Subdistrict in her underwear with chains around her hands and feet screaming for help, according to eyewitness accounts. Police are now searching for a resident named Mr. Chen. He is being investigated for rape and illegally holding a person against their will.

In Chen’s home on the first floor of building D, police found a metal cage that Miss Han is thought to have been kept in. There was blood on the carpet when police searched the apartment.

It’s not like she didn’t scream for help while she was being held, either. Neighbours said Chen’s window had been left open for most of the past few days and they frequently heard a woman screaming, but they figured it was just a typical domestic dispute (which are totally fine, obviously).

Predicatably, Sina Weibo users are debating whether Chen was influenced by Japanese porn. But there are perverts everywhere, and it’s never a good idea for a women to go to a man’s home just after meeting on the internet.

***Update Shortly after 11 p.m. on March 11, Chen was arrested in Guiyang, capital of Guizhou Province. He is thought to be in his 40s and is a native of Shenyang in Liaoning Province.

Also, it turns out Miss Han, from Hunan Province, is just 17.
