The man, identified only by his family name Suh, was found dead at his workplace in a quarry Wednesday morning and his mobile phone battery was melted in his shirt pocket, a police official in Cheongwon, 135 kilometers (85 miles) south of Seoul, told The Associated Press.Source: CNN
"We presume that the cell phone battery exploded," the police official said on condition of anonymity.
The official said the phone was made by South Korea's LG Electronics, the world's fifth-biggest handset maker.
LG Electronics confirmed its product was involved in the accident but said such a battery explosion and death was virtually impossible.
UPDATE: Newer reports indicate the death of the man wasn't caused by an exploding battery but by a co-worker who hit the man with a 15-ton hydraulic rig while driving in reverse. The co-worker later admitted to the police that he had come up with a cover-up for the accident to hide his involvement.
