British police say they have arrested a man and woman for allegedly offering young dance students fake places in the closing ceremony of the 2012 London Olympics.

The Metropolitan Police force said a 35-year-old man and a 31-year-old women were detained Friday in London and Northampton, central England, as part of a fraud investigation.

Police say detectives are investigating "what appears to be a fraudulent offer" of roles in the ceremony to pupils at three dance schools. The police said several businesses had been approached to provide sponsorship.

Detective Superintendent Nick Downing of the force's Olympic unit acknowledged "this will be incredibly disappointing news" for the 75 children aged 9 to 19 who have been tricked into rehearsing for the ceremony.
