South Korean media reports that the second son of North Korea leader Kim Jong-Il was seen at an Eric Clapton concert in Singapore.
Kim Jong Chol, dressed in black pants and a T-shirt, and an entourage of some 20 were seen at the February 14 show.
Attempts to photograph him were thwarted by members of the entourage.
Kim Jong Chol reportedly saw Clapton play a concert in Germany in 2006 and later invited Clapton to come play in Pyongyang.
Kim Jong Chol was once viewed as a possible successor to his father, but youngest son Kim Jong Un has emerged recently as heir apparent.
