“he only stopped after being arrested”
As I said maybe that was the logic being used, perhaps I should have been more specific and said was / is not considered to be a risk.
Perhaps I should have been more specific – he only stopped after the boy spilled the beans and the mother knew.
From the article :
They heard Butt regularly turned up at the youngster’s house to offer his mother a break by taking her son out to the park or arcade.
However, the boy was instead taken to the paedophile pensioner’s house to be abused before being taken out for ice cream as a “treat”.
We have to assume that the mother put a stop to it after the old man was arrested, not necessarily that the old man had suddenly become harmless.
