A Massachusetts man charged in an international child porn investigation has pleaded not guilty to charges of possession and distribution of child pornography.

Geoffrey Portway of Worcester was arrested after state and federal agents allegedly found child pornography and photos of children who appeared to be dead on his computer. Authorities said he chatted online with two men who talked about their desire to abduct, kill and eat children.

Portway is among 60 people who have been arrested worldwide in the investigation. More than 150 children in seven countries have been identified as victims.

The investigation began with the arrest of Robert Diduca, also from Massachusetts. He has been sentenced to 18 years in prison.

A federal judge Monday also scheduled a Jan. 7 court update on Portway's case.
