Prosecutors have confirmed a Chosun Ilbo report of Sept. 6 last year that former prosecutor general Chae Dong-wook fathered a love child.
The Seoul Central District Prosecutors' Office on Wednesday announced the results of a probe into the matter.
Prosecutors presented maternity records of Chae's lover, academic documents of the son, the former prosecutor's signature on medical records of his pregnant lover in 2002, a photo the three took in 2003 celebrating the boy's first birthday, as well as testimony from acquaintances of the woman.
A spokesman for the prosecution said Chae's lover "acted as if the former prosecutor general was the boy's father during every important phase in his life, from birth to his school days, and Chae was understood as being his father not only by the boy but by those around him."
Prosecutors also cleared the Chosun Ilbo of charges of acting illegally in obtaining information or that Cheong Wa Dae sources provided key evidence.
"Chosun Ilbo reporters contacted around 100 acquaintances of the woman, including sources at the child's school, over four to five months and wrote the article based on their findings," the spokesman said.
Prosecutors found that Cheong Wa Dae acted within the bounds of the law in conducting an internal probe of Chae last year following allegations that he violated relevant regulations.
Meanwhile, prosecutors have indicted a former Samsung Group executive for embezzlement after he was caught wiring W200 million to Chae's lover (US$1=W1,024).
Prosecutors said they are investigating charges that the former prosecutor general accepted bribes.
