Inmates threw 'piss and poo' at Hey Dad! star in jail

Robert Hughes starred in the hit Australian series Hey Dad in the late 80s and 90s.

A new book has detailed how sexual predator Robert Hughes has suffered daily in jail, with fellow inmates throwing faeces at his face and urine-filled milk cartons at this shoulders.

The Hey Dad! star was "devastated" after being sentenced in May 2014 to a maximum of 10 years and nine months jail with a non-parole period of six years, for the sexual and indecent assault of four young girls.

A prison guard at Goulburn jail has told how Hughes "sobbed like a big girl" during the reception process and was covered in bodily waste by his fellow inmates as he walked his first walk through the prison yard.

"Piss and poo - they covered him in it. It was his first day in Goulburn and he was brought out into the yard," the guard told James Phelps, author of Australia's Most Murderous Prison - Behind the walls of Goulburn Jail.

The abuse would continue, according to an extract of the book published in The Sunday Telegraph.

As Hughes left his block for the activities yard, he was attacked again, but had no way of cleaning himself until he was allowed back inside to shower. The guard recalls the disgraced star sitting on top of a grassy hill, covered head to toe in human waste and crying.

"He spent the entire time sitting on the hill, sooking. He was a stinking mess," the guard told Phelps.

"It happened again on the way back," the officer said.

"They had reloaded and come back for more."

Shortly after, Hughes could be heard sobbing on the phone to his wife Robyn Gardiner, describing the jail as "hell" and begging her to get him out.

But Hughes has not got out. He remains in Goulburn jail, where the punishments continue - and where he wears a ski jacket in 40-degree heat to protect his skin from the touch of human waste.

• Australia's Most Murderous Prison - Behind the walls of Goulburn Jail by James Phelps is released on August 3.
