Despite the discovery of her body, police made little progress on the whereabouts of the "Black Panther", and it was 9 months later, on 11 December 1975, that he was caught. Having returned to post office raids following the failure of his kidnap attempt, he was finally apprehended by two policemen in Mansfield Woodhouse, near Nottingham, for acting suspiciously in the vicinity of the local post office. A search of his home revealed panther masks, as well as a model of a black panther and, after extensive questioning, Neilson confessed to being the Black Panther. Regarding the murder of Lesley Whittle, however, he claimed her death had been an accident, and that she had been accidentally knocked from the ledge in the drainage shaft.
