Nigerian police have opened a murder inquiry after the discovery of rotting bodies and skeletons in an abandoned building that the media has branded a "House of Horror".
Police also rescued several severely malnourished people found wandering in the bush near the building in the city of Ibadan, while media reports say 15 or more had been found shackled in leg-chains inside.
The grisly discovery comes after a group of motorcycle taxi riders reported that some of their members had gone missing and were believed to have been kidnapped.
"When we got to the abandoned building in the Soka community of Ibadan yesterday (Saturday), we saw decomposed corpses, skeletons and skulls in the building and surrounding bushes," Oyo state police spokeswoman Olabisi Ilobanafor said on Sunday.
"Some malnourished human beings looking like living skeletons were also rescued in the bushes surrounding the building," she said.
Ilobanafor said police had launched a murder investigation and arrested some suspects at the scene in Ibadan, Nigeria's third largest city and the capital of the southwestern Oyo state.
Some victims of kidnapping in Nigeria are often tortured or sacrificed in black magic rituals.
The Ibadan-based Sunday Tribune, Nigeria's oldest private newspaper, showed gruesome pictures of rotting bodies, human skulls and other body parts littering the scene, as well as ID and and ATM cards, shoes, bags and clothes.
It also published a photograph of a haggard woman who was allegedly kidnapped in the southern Edo state in 2008 and rescued at what it called the "House of Horror".
Some other local newspapers carried similar reports about the discovery.
