Natneal Yemane, 15, an Ethiopian, carried the torch as part of the International Inspiration programme, a games sponsored initiative to encourage children at home and abroad to do more physical exercise.
But shortly after completing his section of the relay in Nottinghamshire, he has disappeared and police have launched a search.
It is not believed any foul play has taken place and officials believe he has family in London.
Officers said he left the hotel where he was staying, the Jurys Inn, Waterfront Plaza, Nottingham, at around 9.15pm yesterday and did not return.
