Update as of 4:07 a.m. EDT: The director of the State Administration of Work Safety in China, Yang Dongliang, is being investigated by the Communist Party of China's (CPC) Central Commission for Discipline Inspection (CCDI), state-run news agency Xinhua reported.
The investigation is related to last week's Tianjin explosions, which killed over 100 people, left nearly 70 people missing, and caused widespread damage in the port city. The CCDI said that Yang is being investigated for suspected "severe violation of discipline and law," according to Xinhua.
A Reuters report said that the CCDI did not give any further information about the blast while Yang was not reachable for a comment.
The president and the vice-president of Ruihai International Logistics Co. Ltd, where the Tianjin blasts occurred last week, have been detained, China’s state-run news agency CCTV said in a tweet Tuesday.
Multiple blasts rocked a chemicals warehouse, owned by Tianjin Dongjiang Port Ruihai International, in the Chinese port city last Wednesday, killing 114 people and injuring hundreds. An area of more than 1.8 square miles near the blast site was destroyed, leaving 6,000 people homeless.

The government said Monday that it is investigating the cause of the massive explosions, amid rising public anger. About 70 people, including firefighters and police personnel, are still missing, nearly a week after the blasts.
