Believe nothing police investigators have to say, they lie to "persons of interest"as a matter of course. I worked with investigators for almost 10 years, I know what they do in interviews. Again, my advice to anyone who is ever read (advised of) their rights is to say nothing, but: "I want a solicitor. I want a solicitor. I want a solicitor!!" Don't say anything but basic information, name, place of residence, until you get legal representation.
