Six inmates took the warden and several other people hostage at a prison in the southern Taiwanese port city of Kaohsiung on Wednesday afternoon, the official Central News Agency said.

It said two people might be injured but gave no further detail.
CNA said the inmates were demanding a vehicle that could allow them to leave. It said police were on the scene confronting the inmates.
Police were investigating the reason for the hostage taking, CNA said.
