CAGAYAN DE ORO CITY - The lifeless body of inmate Wilfredo Taban, 54, was found in a detention cell in the Macabalan Police Station on Thursday.
"Bennie," another inmate, said he tried to wake Taban but got no response.
Bennie said Taban did not show any symptom of illness.
No signs of foul play were found in Taban's body and he may have died from natural cause, Dr. Christian Caballes of SOCO said.
According to Chief Insp. Ernesto Daing, station commander of Macabalan Police Station, he wants to eliminate concerns that the police had something to do with the inmate's death.
Taban was arrested last Tuesday for illegal possession of drugs.
