Kenneth Fenske, 57, was the fifth suspect arrested in an alleged pedophile ring in which men dressed up as furry animals and assaulted a young boy

A suspect in a fetish-themed child predator sex ring, in which men dressed up as furry animals and assaulted a young boy, was arrested on Friday.

Kenneth Fenske, 57, was arrested in Quakertown, Pennsylvania, 45 miles north of Philadelphia.

He was the fifth suspect apprehended in what police said was the years-long abuse of a young boy, who is now 14, at sex parties where men dressed as animals raped him.

Fenske was charged with child rape, involuntary deviant sexual intercourse and unlawful contact with a minor, CBS Local reported.

Other suspects arrested and charged in the abuse include Jeffrey Harvey, left, and David Barker, right

Fenske's name at these furry parties was allegedly 'Lupine' and he dressed as a furry red fox.

On 'three or four' occasions he stands accused of undressing a boy who was brought to the parties at the man's house dressed as Tony the Tiger, the Philadelphia Inquirer reported.

The boy would play Xbox at Fenske's house and Fenske occasionally take the boy to his bedroom to abuse him, it is alleged.

Since last summer, Jeffrey Harvey, David R. Parker, Craig Knox and Stephen Taylor have been arrested and charged for their alleged participation in the abuse of the boy.

Knox would dress as a rottweiler and kept nine such dogs at his Virginia home and Taylor is accused additional bestiality-related crimes.

Pennsylvania Attorney General Josh Shapiro said: 'This child victim was repeatedly abused over a seven- or eight-year period by a group of criminals who cared only about their gratification.'

Parker, Harvey and Knox are in custody while Fenske and Taylor posted bail and await trial.

The investigation is ongoing and prosecutors believe the case may involve both more victims and more predators.
