Eagle Hotel Bombing ,King's Lynn June 12th '42

Morning folks,I am looking for some information regarding the above with regard to which type of aircraft was used and if possible the squadron.The Eagle’s bombing was very unfortunate as the rest of the stick of bombs had fallen mainly on open ground but the last bomb dropped managed to hit the hotel which was hosting a party at the time and a few service personel within the pub were killed.My research so far has drawn a blank with regard to type but the Do 17 has been suggested but i suspect this is wrong.My grandmother observed the bomber passing between the clouds as it passed over the town but as would be expected couldn’t tell me what it looked like.Many thanks in advance.
