While Neil was teaching in Thailand, he allegedly employed the services of a Thai to bring young boys from Internet Cafes to his apartment to perform sexual services. As Neil arrived at the Royal Thai National Police Headquarters he was swarmed by a battalion of around 300 journalists wielding cameras, which resulted in a stampede.

On January 11, 2008, the start of his trial was set for March 10. He pleaded not guilty. On March 10 it was found that Neil did not have a lawyer. One was assigned to him and the trial was adjourned to June 2. He was sentenced on August 15, 2008 to 39 months in prison and $1,780 fine. His original sentence of 6 years was reduced by about half because he admitted to the crime. On November 24, 2008, his sentence was extended by six years following his conviction for molesting a second child.

Extended search for others

Thai police expanded the hunt for potential child sex offenders by publishing photographs of 50 Western suspects identified by international authorities, many of whom are German citizens. Other nationalities include British, Australian, Italian, Finnish and American. On the 6th of May, 2008, Interpol launched Operation IDent, its second public appeal to identify an unknown child abuse suspect, who featured in almost 100 images showing the sexual abuse of at least three boys between six and ten years old. After receiving more than 250 leads, Wayne Nelson Corliss was arrested by ICE agents in New Jersey, and charged with producing child pornography, admitting sex with three boys and denied bail. November 2009, he was sentenced to 19.5 years in prison.

Reverse swirl transformation

The "swirl" operation allegedly used by Neil to disguise his face in photographs is in theory non-lossy: that is, information about the original image is not lost and can be perfectly restored from the altered version. In practice both resolution

 make the operation slightly lossy, but it is reversible by applying the same operation with opposite rotational direction and the same intensity.

Although exact steps may vary, this disguise and restoration can be made by following these steps:
  1. Apply the twirl filter with x degrees settings to the picture. This should distort the picture.
  2. To un-distort, apply the twirl filter with -x degrees setting. Alternatively, one can vertically flip the picture and apply the first twirl filter (with x degrees) again.


When starting with a "pre-swirled" image, the reversal may not be as easily done as the example shown to the right, as the settings of the initial swirl are not known. The correct position, area of effect and intensity (angle) of the swirl must be determined in order to cancel the initial swirl successfully, possibly by trial and error
