Two Muslim teenagers have admitted drawing burkas on advertisements of scantily-clad women because they offended their religious views.
In one incident, Mohammed Hasnath and Muhammed Tahir, both 18, used black paint to draw the traditional headdress over a model in a poster for Lynx deodorant.
The vandals said it was a 'sin' for the woman to remain uncovered and they were 'just trying to do good'.
