"We can confirm that the Prosecutor General's Office has received a request from Uzbekistan to provide legal mutual assistance, which is currently being studied," the office said.
The Prosecutor General's Office also noted that a criminal case on suspicion of money laundering was opened in Switzerland in July 2012 against six people, including Karimova.
"To date, the Prosecutor General's Office has frozen assets worth more than 800 million Swiss francs. Since the opening of the criminal case in Switzerland, the Prosecutor General's Office has conducted procedures for providing mutual legal assistance with 19 countries, including Sweden, the Netherlands and the United States," the office said.
Earlier in the day, the Uzbek Prosecutor General's Office said that Karimova was charged under several articles of the Criminal Code and put into pre-trial detention. The assets of the criminal group, in connection with which she was accused, have been identified in 12 countries, including Russia.
According to the Prosecutor General's Office, during the investigation of the criminal case on tax evasion against three private companies, it was established that Karimova could directly contribute to the criminal activities of the organized group.
In particular, in Switzerland, assets worth $777.8 million and villas worth 18.5 million francs were identified. The criminal group also owned monetary funds and real estate in France, Hong Kong, Sweden, the United Kingdom, Latvia, Ireland, the United Arab Emirates, Malta and Spain. On the territory of Russia, the investigative bodies of Uzbekistan have identified assets in the form of money worth $6 million and various real estate.
The Russian Prosecutor General's Office said that has not yet received a request regarding the possible arrest of Karimova's assets.
