China's top procuratorate accused 11 officials and port executives of neglecting management of dangerous chemicals storage and transportation in the Tianjin port, where explosions killed 139 and devastated the port area.

The officials from various government departments, including Tianjin local transportation management authorities, work safety regulatory agencies, land resources authorities, Tianjin local customs office and a state-owned port company, were probed for "dereliction of duty" and "abuse of power," according to a statement from the Supreme People's Procuratorate on Thursday.

The prosecuted officials included Wu Dai, head of Tianjin Municipal Transportation Commission, and Zheng Qingyue, president of Tianjin Port Holdings Co., Ltd.

The police detained 12 suspects from Tianjin Ruihai International Logistics Co. Ltd, owner of the exploded warehouse that allegedly handled dangerous chemicals.

The police said the company and the detainees were suspected of illegally storing dangerous materials. The detainees included board chairman Yu Xuewei, vice board chairman Dong Shexuan and three deputy general managers.

The police also announced the investigation of Tianjin Zhongbin Haisheng, a company suspected of illegally helping Ruihai acquire safety evaluation papers.
