"Uttam Rayamajhi, 17, vanished from the team ski base at Les Arcs on Monday with no money, minimal French and very little clothing. He has not been seen or heard from since and team members fear for his safety," Richard Morley said in a statement, according to the news agency.
"He was approached by Jehovah´s Witnesses and recruited into their church. The day after attending his first service with the sect he vanished from the team´s mountain chalet home during a heavy rainstorm.
"Despite extensive efforts by the police at Bourg St Maurice, no trace of him has been found."
Morley told Reuters by telephone that Rayamajhi had been extremely distressed lately following the disintegration of the Nepal ski team in the wake of a funding row with the Nepal Olympic Committee.
Morley, a British businessman and former skier, launched the Nepal Alpine skiing team in 1997 at the request of the Himalayan country´s then king Birendra Shah.
Jehovah´s Witnesses was not immediately available for comment about Rayamajhi.
