Kim, along with partner Park Joo-bong, won his nation's first gold in the men's doubles on the sport's official debut at the Games in the Spanish city 23 years ago.

He also won two World Championship doubles crowns, in Calgary in 1985 and in Copenhagen in 1991, as well as a string of other international honours.

The 51-year old is suspected of hitting the 29-year-old victim, identified only by his surname Park, on several occasions after supposedly quarreling over a bar tab at around 3am.

The incident allegedly took place in the Gangwon Provice town of Wonju to the south of Seoul where he is staying ahead of next week's National Sports Festival.

Kim was entered into the Badminton Hall of Fame in 2002 and since then has enjoyed success as coach of the Samsung Electro-Mechanics badminton team.

But this is not his first brush with controversy, having been suspended for two years - reduced from a life ban - for his involvement in the infamous scandal in which two South Korean pairs at London 2012 were adjudged to have deliberately lost matches in order to ensure easier draws later in the competition.
