According to the Yonhap News Agency, the raid is linked to charges brought against Cho's wife earlier this month — she allegedly falsified papers that helped her daughter get admitted into the medical faculty of the prestigious Korea University in 2010.
The prosecution suspects that Cho and his wife could have destroyed evidence.
The minister refutes the allegations and is considering legal action over those media reports that led to the prosecution's raids.
Cho, who took office on 9 September pledging to reform the Prosecutors' Office, previously served as President Moon Jae-in's aide for civil affairs.
