Hi,
They may well be a PoW debriefing report for him at the National Archives. It is possibly in the WO344 files, however, if he evaded for some time there may also be a report in the WO208 files. I haven't looked at PoW reports, but there is a card index to most of the WO208 files in the NA, although the latter series of files in WO208 (the Liberation reports) are not indexed.
I posted a link under Escape and Evasion reports to a website where some of the indices to the WO208 files can be looked at and you might find his name there, although I would think it more likely that any file is extant is in the WO344 series.
Best of luck,
Ann
