MR KAHANOVITZ
Yes, but you'd only be in a position to tell him that if you'd taken steps to attempt to establish his movements, his whereabouts and you would then say to Mr Verster:  "We have been looking out for the man, Mr So-and-so's been sent round, his house has been watched, his flat has been watched, his telephone has been bugged.  Unfortunately, after having taken all of those steps, we can't find him."
