Bangladesh police Wednesday found the body of a Chinese businessman who was murdered and his body dumped in an upscale Dhaka neighbourhood, officials said.

Acting on a tip-off, police and an elite security unit recovered the body of Gao Jianhui buried in a residential backyard outside his home in Banani, local police chief Nure Azam Mia told AFP.

"It is a murder case. He was killed sometime yesterday evening," he said. Gao, 47, who had been living in the Bangladeshi capital for several years, supplied stone for some key Chinese-financed projects including the country's largest bridge and one of the biggest coal-fired power plants, police said.
