lugovoi had done very well in business after that and opened a security consulting firm. he says he and litvinenko met several times in london to discuss doing business there together including that now infamous meeting in the pine bar where scotland yard says litvinenko was poisoned. lugovoi says the meeting was no big deal. so what do you remember about sitting there at the table? >> translator: i remember that we talked with litvinenko about nothing in particular. and now for eight years, i am under suspicion. >> reporter: you're under suspicion because the investigation says there was polonium in that teapot. did you put any polonium in the tea? >> translator: of course not. i was tested for polonium, and i tested positive. did i put polonium into myself? am i an idiot? am i crazy? >> reporter: but scotland yard detectives don't believe lugovoi's denials.
