Cambodian authorities have detained a fifth suspect in the 12-year-old kidnapping and murder case of two men who were clearing land mines.

Former Khmer Rouge fighters abducted Christopher Howes of Bristol, England, and his interpreter Huon Huot along with other members of a team removing land mines near Cambodia's Angor Wat temple in 1996.

Most of the team was released, but evidence later showed Howes and Huot were executed in rebel-held territory.

Cambodian authorities took 52-year-old Puth Lim into custody and charged him in the case Friday. Five other former Khmer Rouge fighters also face charges which could carry a life sentence if convicted.
