The estranged boyfriend of a woman whose body parts were found scattered around Toronto has been arrested and charged in connection with her murder, police said Monday.

Police Insp. George Koekkoek said 40-year-old construction worker Chun Qi Jiang has been charged with second degree murder in the killing of Lui Guanghau, a single mother of three.

Koekkoek said both the victim and suspect are Canadian citizens of Chinese descent. The couple dated for four years and recently broke up.

Lui's head, foot and hands were discovered in a river west of Toronto earlier this month. A few days later her two calves, a thigh and an arm were found in a creek in eastern Toronto.

The 41-year-old was last seen alive Aug. 10 when she was dropped off by friends at the spa she owned.

The discovery of body parts received extra attention following the case earlier this year of porn actor Luka Magnotta, who is accused of dismembering a Chinese student in Montreal and mailing his body parts to political parties and a school. Police have ruled out any connection between the cases.

Police still do not know how Liu died. Parts of Liu's body have yet to be recovered.
