Controversy has trailed the death of a former governor of Osun State as his remains were taken to Ladoke Akintola University Teaching Hospital for autopsy.
Mr Adeleke, a serving senator, died at the age of 62 at Bikets Hospital in Osogbo, the Osun state capital after suffering heart attack.
This is against the expectation of sympathisers who waited as the body was earlier being prepared for burial, according to Islamic rites.
The autopsy option, sources say, is being taken following rumours that he was poisoned at a political meeting on Saturday.
Mr Adeleke was preparing to run for the Osun governorship election in 2018 before his death on Sunday morning.
He was earlier brought home from the hospital amidst wailing and weeping by supporters and family members.
The development has resulted in a traffic gridlock across the streets of the town. Supporters are also lighting bonfires across the town to register their anger, raising fears of possible violence.
