The first two sources said prosecutors and the party's anti-corruption watchdog had frozen bank accounts with deposits totaling 37 billion yuan and seized domestic and overseas bonds and stocks with a combined value of 51 billion yuan after raiding homes in Beijing, Shanghai and five provinces.
Investigators had also confiscated about 300 apartments and villas worth around 1.7 billion yuan, antiques and contemporary paintings with a market value of 1 billion yuan and more than 60 vehicles, the sources added. Other items seized included expensive liquor, gold, silver and cash in local and foreign currencies.
The seized assets belonged to those in custody, the sources said, without saying how many people in total had been detained compared to just questioned. Most of the assets were not in Zhou's name, they added.
