Police in southern Bangladesh say a woman cut off a man's penis during an alleged attempt to rape her and took it to a police station as evidence.
The incident took place in Mirzapur village, Jhalakathi, about 200km (124 miles) south of the capital, Dhaka.
Monju Begum, 40, a married mother of three, told police that neighbour Mozammel Haq Mazi forced his way into her shanty and started assaulting her.
Mr Mazi, who denies the accusation, has been admitted to a nearby hospital.
"We will arrest him once his condition gets better," police spokesman Abul Khaer told the BBC.
"She said she fought back and cut off his penis and brought it to our police station in a polythene bag to prove that Mr Mazi tried to rape her," police spokesman Abul Khaer told the BBC.
