A top Russian prosecutor is reportedly willing to provide Swiss investigators with documents relating to a money laundering case involving a former high ranking Kremlin official, Pavel Borodin.
On Wednesday, the Russian news agency, Interfax, quoted the prosecutor, Ruslan Tamayev, as saying that he would hand over documents requested by Swiss officials.
Borodin was arrested in New York on a Swiss warrant last month, and is awaiting extradition to Switzerland on suspicion of money laundering.
According to another Russian news agency, Itar-Tass, Borodin is likely to remain in the US at least until the end of April. The agency quoted Tamayev as saying that the magistrate handling the case had set a new date of April 30 for the extradition hearing.
Russian prosecutors, who were also investigating allegations against Borodin, dropped their charges last December, citing lack of evidence.
Swiss officials say they have evidence that Borodin had access to Swiss bank accounts containing about $25 million (SFr42 million), and that the money has now disappeared.
They suspect that Borodin received the money in kickbacks from two Swiss-based firms, in return for lucrative contracts to renovate the Kremlin.
For seven years, Borodin was Kremlin property chief under the former Russian president, Boris Yeltsin.
