A university in central China's Hubei Province lifted blockade and resumed normal operation Wednesday afternoon after a hostage taker was shot dead by police earlier in the day.

The hijacker's body is taken out.

The school authority released a statement on its website about the incident and is trying to appease the hostage, surnamed Liu.

A man took a female staff member hostage at gun point in an office in the Wuhan University at 9 a.m.

Police negotiated with him for several hours but found he had no clear demands. He appeared very agitated and sometimes hallucinatory, said Xia Zhigang, vice director with the Public Security Bureau of Wuhan, the provincial capital.

In the rescue operation, an armed policeman Tan Jixiong was disguised as a canteen man bringing him a meal. He entered the room at about 2:50 p.m., but was shot in the head by the hijacker.

Police waiting outside the room immediately shot and killed the hijacker. The female staff, who work on Communist Party affairs, was unharmed.

Tan was seriously injured but remained in stable condition after the bullet was taken out of his head in a first aid treatment in hospital. He has to undergo a second operation on his chest.

The hijacker, Zhou Kai, 40, used to serve in the armed police force before he joined the university as a logistical worker.

He was sentenced to two and a half years in prison for illegally confining others in July 2008, with a three-year reprieve. He was still under police supervision. He was a drug user before, according to Xia.

Police are still investigating the case.
