A Japanese businessman was shot to death during a robbery early Sunday on a street in Phnom Penh, local police reported.

Kosei Kitakura, 43, was attacked by two unidentified men on a motorbike who fired at him as he tried to fight them off, according to the police. He died on the way to a hospital, and the two suspects remain at large.

Heang Thareth, deputy police chief of Phnom Penh's Chamkamorn District, said the assailants set upon Kitakura soon after he got out of a tuk-tuk taxi in front of his apartment building. Kitakura had arrived in Cambodia on Wednesday to help set up a local company.

The driver of the vehicle sustained injuries to his left arm while attempting to come to Kitakura's rescue, the deputy police chief said.
