An orangutan chained to bed, shaved daily and forced to have sex with men for years, has finally undergone rehabilitation after it was rescued from its kidnapper.

The animal, named Pony, was captured and “treated as a prostitute” by her kidnapper, who pimped her out to clients.

The sickening abuse carried on for years before she was finally freed.

Rescuers discovered Pony’s body had been shaved and she was covered in painful bites.

It took the intervention of police and military officers to persuade the homeowner to allow the orangutan to leave.

During her ordeal, Pony was made to perform sex acts on men and it has taken more than a decade to rehabilitate her.

She was brought to the Nyaru Menteng centre in Borneo, Indonesia, where workers were alarmed at the damage done to her.

Pony showed no desire to explore and was not able to forage for food herself.
