As in the Galleon case, investigators used court-authorised wire taps of cell phones, hidden recording devices and information from confidential informants to build the case against at least seven of the new defendants named yesterday. 与帆船集团的案件一样,调查人员在法庭的授权下,使用手机窃听、暗藏录音装置和秘密线民提供的信息,针对昨日指名的至少7名新被告人进行取证。
