In the case of Norwich this process was underscored later by the arrival of Dutch and Flemish "Strangers" fleeing persecution from the Catholics and eventually numbering as many as one third of the city's population

Andrei Sawoniuk was born in Domaczewo, Poland (now Damachava, Belarus), a spa town on the Bug River...During World War II Sawonuik was a member of the local Nazi-supported Belorussian Auxiliary Police...After the war Sawoniuk settled in England in 1946, posing as a Polish patriot...it took until 1993 for authorities to realise that Sawoniuk, then working for British Rail, was one of the people on the KGB list and was duly arrested...He was the first and the only person in United Kingdom to be convicted under the War Crimes Act 1991. From a legal perspective this case is interesting as it was also the first time that a British jury had travelled overseas to view the scene of a crime...Sawoniuk died in Norwich Prison of natural causes aged 84.
