Concerns are growing from friends and the public for the well-being of Kenyan marathon ace Wilson Kipsang.
The former marathon world record holder appeared to be drunk during a TV interview about his recent four-year ban from athletics.
Kipsang, who is a policeman, is yet to respond to BBC Sport Africa's request for a comment about his TV appearance.
Elias Kiptum, a friend of Kipsang's, told BBC Sport Africa he is concerned about the athlete.
"He's tried to control his stress by drinking and this is what it has become a worry to us," he said.
