Police say they have arrested a woman in the southern Pakistani city of Karachi suspected of murdering her husband, then chopping his body into pieces and boiling them to try to get rid of the evidence.

Police officer Khalid Nadeem Baig said Friday that 42-year-old Zainab Bibi told authorities she killed her husband because he tried to sexually assault her 17-year-old daughter from another marriage.

Baig said Bibi sedated her husband by mixing sleeping pills in his tea and strangled him with rope. She and her nephew allegedly cut up her husband and boiled the flesh.

Police say they discovered her plot after neighbors complained about a bad smell coming from her home. They also arrested the nephew.
