据《环球邮报》(The Globe and Mail)报道,按照安省证监会向多伦多法庭提供的文件显示,谭耕曾为龚晓华担任中间人,亲手向加拿大驻北京大使馆副大使杜欣丽(Cindy Termorshuizen)递交一封由龚晓华所写的信件,杜欣丽将信件交给加拿大皇家骑警在中国的联络官,后者再将信件转给加拿大调查人员。另外,报道指谭耕也曾代表龚晓华与中国当局谈话。
谭耕于电邮中强调:「我只是代一名居于多伦多-北约克社区人士,转递一封函件而已,当时我并不知道有本国执法部门正向其进行调查,故任何对此事件之推论都不正确。」(”I simply transported a piece of correspondence on behalf of a fellow member of the Toronto-North York Community. I was unaware of any Canadian investigation into this individual. Any inference of influence in this matter is simply wrong. ” )《环球邮报》向谭耕作出相关查询时,也是收到上述的电邮回覆。
