Osprey 9 says more or less the following:
Mosquito crew were directed to a contact, which was Ju 188 E-1 3E+BK of 2./KG 6 (Leutnant G. Lahl). Mosquito chased e/a through tight turns and steep climbs before firing multiple bursts from 250 yards astern. E/A crashed and exploded near Butlers Farm, Shopland, Essex, with four crew KIA and one POW.
Aces High gives the location as Great Wakering.
Also note that Bunting and his radar operator (F/L C.P. Reed according to another of Martin Bowman's books) also shot down a Ju 88 at about 00.45, details here:
