A Peruvian woman was so angry when she discovered her boyfriend was cheating on her that she did the unthinkable.

Julia Muñoz Huaman, 41, and her boyfriend Ramon Arias Apaico, 46, were staying in a Brena hostel when an enraged Huaman grabbed a knife and severed Apaico’s penis while he slept.

The angry girlfriend then flushed the member down the toilet and attempted to leave.

Before she could escape however, the hostel’s staff heard Apaico’s pain-filled screams, stopped Huaman and called police.

Though the penis was not recovered, doctors at Loayza hospital in Lima say he remains “partially intact”. He is expected to remain hospitalized for another week, but will likely need psychological treatment for quite awhile.

When Huaman was questioned by police she admitted to mutilating Apaico’s genitalia after growing enraged at the news of his infidelity.
