A 19-year-old Chinese student recorded the killing and dismembering of her married lover by her boyfriend, local media said on Friday.

The second-year student in the southwestern province of Yunnan, her boyfriend and another male accomplice had all been arrested after the killing last month, the Southern Metropolis Daily said.

The victim, 39, was a married manager at a local highway and bridge building company, the newspaper said.

The girl, who was from a struggling family in the capital Beijing and met the victim as a nightclub hostess, filmed as he was killed and his body was cut into "hundreds of pieces," the newspaper said. "The dismembering was both out of hatred and aimed at making the body unrecognisable," the report said.
