A Swiss official says Roman Polanski can only be sentenced to two years in prison in the U.S. for having sex in 1977 with a 13-year-old girl. Justice Ministry spokesman Folco Galli told Europe-1 radio that Polanski could only serve time in California for crimes included in a U.S. extradition request filed late Thursday. Galli didn't say specifically whether Polanski was being pursued for fleeing justice in 1978. But he said Polanski declared himself guilty to sexual relations with a minor and the maximum sentence for that crime is two years.
