Kampusch kidnapper 'was in child porn ring'

A man who held a young woman captive for more than eight and a half years may have been involved in a child pornography ring, police said today.

Franz Lang, the new chief of Austria's Federal Criminal Investigations Bureau, said the investigation into Natascha Kampusch's captor has yielded "suspicious factors" suggesting a child porn element.

He said the case has produced "widening circles" that need further investigation.

Wolfgang Priklopil kidnapped Miss Kampusch when she was walking to school at the age of 10, and held her in a windowless cell.

Miss Kampusch escaped in 2006, and Priklopil committed suicide by jumping in front of a train.
