On Tuesday, the Chinese Embassy in Germany received a report from the Chinese student union of Friedrich Schiller University in Jena. The report stated that a Chinese student surnamed Liu, who came from Shanxi province, had been killed, according to a statement published on the embassy’s website.

The embassy said it sent staff to get more information and urged local police to investigate the case.
