The wife of the famous Nazir Rav Dovid Cohen [died 28 Av 1972] relates that one time he was sitting in his apartment learning. The British suspected him of hiding members of the Etzel underground in his apartment. So a British officer tried to enter the apartment to conduct a search. The Nazir's wife said "Stop. There is a Rabbi here who is learning". He was not fazed and pushed her aside.
When he saw the Holy Nazir, long hair and all, he crossed himself and cried out "Holy Man". He then placed a guard outside the building to make sure that nobody would bother the "Holy Man".
