Last year a fugitive on the UK’s ‘most wanted’ list was finally apprehended after spending 27 years on the run.
80-year-old Richard Burrows was arrested at Heathrow Airport on March 28 and charged with a number of crimes relating to the historical abuse of children that allegedly took place between 1969 and 1971.
It meant that the National Crime Agency, who are responsible for fighting serious and organised crime, could tick a name off their list of most sought-after criminals and suspects.
But they are still hunting many more - with some from Scotland, or having been suspected of carrying out serious crimes in Scotland.
Here’s who is currently on the list. All these men are dangerous, so do not attempt to approach them and instead immediately call ‘999’.
