A Canadian pedophile who was tracked down after "swirled" images of him were unscrambled has been convicted of abusing a second child.

A global search led to the arrest of Christopher Paul Neil, 33, in Thailand in October 2007 and was sentenced to more than three years in prison for abusing a 13-year old Thai boy.

Thailand's Criminal Court has since found him guilty of three more charges of also abusing the victim's brother, who was nine at the time.

The verdict, which had not been previously released, found Neil guilty of abuse and illegal detention of a minor. The former teacher was given a nine-year prison sentence, but he will serve only six years and his two sentences will run consecutively.

He had confessed to molesting the older brother but denied the charges in his second case.

Neil, 33, from Vancouver, was arrested after Interpol launched a public appeal seeking help in identifying a man seen in about 200 graphic online photos abusing Asian boys.

The man in the pictures had created a digital swirl to hide his face but German computer experts were able to reconstruct the images.
