After a woman in Pakistan found out that her husband wanted to leave her for a fourth wife, she took matters into her own hands by beheading him, chopping up his body and then dumping the parts in a sewerage drain.

Local Police say Majeeda Khatoon killed her husband, a well-off building contractor, while he was asleep, and cut his body into seven pieces with the help of two male relatives in Gulshan-e-Hadeed, a suburb on the outskirts of Karachi, according to Reuters.

"When we questioned her, after the deceased's brother came to us for help, she confessed to the crime," police official Nazar Mohammad Mangrio said on Wednesday.

Khatoon, 45, was arrested late last week and has been remanded while police confirm charges against her.

Polygamy is nothing of a surprise in Pakistan, as Islam permits men to take up to four wives.
