Police have been investigating allegations that some singers had to pay bribes of up to $85,000 to perform in the San Remo festival, Italy's most popular annual pop-song contest.

Court sources said Monday that the results of the two-month investigation have been given to Ugo Giudiceandrea, the chief prosecutor in Rome, who will decide whether to file charges.Police said the charges under consideration include extortion and fraud.

Police sources in this gambling resort along the Italian Riviera indicated that little-known singers and their recording companies paid bribes ranging from $42,500 to $85,000 to appear in the contest.

The show can boost a singer's popularity and royalties because it is telecast nationally on the state-controlled network for three straight nights.

The Italian media has identified a few singers and some companies that have contended they paid bribes, but police have not confirmed the reports.
