Looking at Martin Middlebrooks's Bomber Command War Diaries the night of 3/4th April 1945 is listed as minor operations.
95 Mosquito sent to Berlin, 8 to Plauen and 5 to Magdeburg with 17 Mosquito Nightfighter patrols.

Heavy RAF daylight raids looked to have taken place on the 3rd and 4th,
and a major night raid was flown on the 4/5th deep into Germany.

I was going to suggest and RAF Airgunner could have shot down the 110 without actually being aware he had scored enough or any vital hits, however if the above details of 3/4th night are accurate it would appear that no RAF gunners were over Germany that night.

Possible friendy fire or German Flak hit if the date is correct ?
