Police and the ambulance service arrived at the scene and paramedics treated him at the scene before he was taken to hospital.
Convamore Road was cordoned off, with motorists being turned around.
Detectives were seen conducting door to door enquiries as they waited for Crime Scene Investigators to arrive.
It is believed the man was being held against his will at the house after being forced to leave another address in Cleethorpes earlier on Saturday.
The image, caught by a shocked passer-by, shows the man naked near the Lifestyle Express corner shop on the corner of Convamore Road and Ropery Street. His left lower arm is hidden by his body but in his right hand he appears to be carrying something.
There are reports he had been beaten in the house, possibly by two men, before he managed to escape by throwing himself through the window.
The house across the road from the shop had its ground floor window almost completely smashed out. It was sealed off by police after the incident.
Ogun police spokesperson, Abimobola Oyeyemi said the suspect who is a resident of 7, Odunsi Street, Ijebu Igbo area was arrested on Monday November 23 after being seen with a bag suspected to contain stolen property.
“The suspect was arrested after the incident was reported at Ago Iwoye division that a man was seen with a bag suspected to contain stolen property, and when he was challenged, he dropped the bag and ran into the bush.
“Upon the report, the DPO of Ago Iwoye police station, CSP Paul Omiwole, led his detectives to the scene where they opened the bag and discovered that it contains dry human parts.
“Consequently, the bush he ran into was properly combed and the suspect was apprehended.”
Upon being interrogated, he confessed to have harvested the human parts from one Christian cemetery in Oke Eri, Ijebu-Ode together with one Lekan Bakare who is now at large. The Ogun Commissioner of Police, CP Edward Ajogun has directed that the case be transferred to the state CIID for further investigation and prosecution.
