On Sunday, following Wednesday's massive explosions that devastated the northeastern coastal city of Tianjin, China, Chinese authorities have arrested some of the top officials who work for the company believed responsible.

The Xinhua news agency, as reported by the BBC, is now saying that the Chinese firm whose warehouse exploded did not have a license to handle hazardous chemicals until two months ago. As recently as eight months before getting their license in June, the Tianjin International Ruihai Logistics was handling hazardous chemicals without the proper documents.

CNN has reported that, according to state media, 10 senior executives of the company that owned the warehouse site that exploded have been detained. Among the executives being held for questions are the president of Tianjin Dongjiang Port Rui Hai International Logistics Co., as well as the company's vice president, Cao Haijun, and its chief financial officer, Song Qi.

The executives have been detained since Aug. 13.

Officials have said that the warehouse was a temporary storage facility, which housed materials after arriving at the port. As the process of cleaning up has gone on, several hundred tons of highly poisonous sodium cyanide have been found.

A commentary regarding the aftermath of the horrific mishap written for China’s official paper, the People's Daily, says tha: "Many are questioning about the number of people killed in the blasts, the emergency assistance provided, and the handling of the aftermath. Some are even suspicious, with rumors circling."

The statement concluded by saying that: "In the face of an accident that has caused heavy losses of life and property, the central government's attitude is clear and resolute: a thorough investigation and severe punishment are beyond any doubt."

The Chinese authorities had earlier acknowledged that they were not clear as to what was being stored in the warehouses run by Ruihai International Logistics.

As quoted in the Independent, Gao Huaiyou, the vice head of Tianjin’s safety watchdog organization, said, “The information the management of the company provided is not consistent with our investigation.”
