In an alleged robbery gone wrong, the robber had part of his penis bitten off by his victim at Abompey New Site in the Obuasi Municipality of the Ashanti Region.

Justina Donkor, a 24-year-old student, reported to the Police that Emmanuel Ankron, 23, drugged and forcibly had sex with her in her room.

The lady claimed she woke up to find the man holding a machete and pointing a locally manufactured pistol at her.

She alleged that Mr Ankron had robbed her of an amount of ¢550, her TV set and mobile phone.

In her statement to the police, she said her assailant later changed his mind to leave the room with his booty and asked his victim to play with his private part.

Although unwilling, she obliged and started and in the process, she bit off his penis. The suspect also allegedly bit her at the back.

"The suspect, with blood oozing from the wound, ran away leaving the TV set and her mobile phone behind," she said in statement to the police.

Both of them are receiving treatment at the AGA Hospital.

The police have retrieved the cut off penis from the crime scene and deposited it at the hospital for preservation.

They say investigations are underway.
