Hello Ian / Ulf – Any more info. on this post, my uncle was on board that aircraft and sadly didn’t survive the crash. There is a reference on this site; 

https://aviation-safety.net/wikibase/216388 which claims the plane was shot down by night fighter pilot Oberfeldwebel Wilhelm Schulte-Heinrich of the 7./NJG 2, flying a Bf 110G from probably Venlo airfield, the Netherlands.
