On Schedule 1, Background/Declaration, question 9. If you were "detained or put in jail" but you do not know exact dates, or even if there were any charges laid, (just questioned) what would be the best thing to put in the explanation. The police certificate shows it is clear and a request for any arrest record shows it is clear (they clear it after 5 years have passed) but still don't know if there ever was a record. Don't want to lie on the form but don't really want to make the background check drag out any longer then necessary either. :'(
