TAIPEI - Huang Shyh-ming, chief of Taiwan's prosecutorial authority, on Friday was accused by the district prosecutors office of Taipei for leaking confidential information.

An investigation of Huang's case concluded on Friday. Local prosecutors believe that Huang briefed Taiwan leader Ma Ying-jeou on information about an ongoing probe of an illegal lobbying case that involved Wang Jin-pyng, the island's chief legislator, according to a Taipei prosecutors office press release.

Prosecutors have accused Huang of leaking confidential information. Relevant information about an investigation is classified as secret before it is concluded.

Prosecutors believe that Huang's arbitrary behavior may lead to a public misunderstanding that Ma intended to obstruct the course of justice, according to the press release.

Last month, Ma and Jiang Yi-huah, chief of Taiwan's administrative authority, were questioned as witnesses in the investigation of Huang's case.
