A cowardly prisoner hurled a bucket full of faeces and vomit over a prison officer, getting some of it in her mouth and eyelash.
Thomas Guest called the name of the female officer at HMP Channings Wood, luring her into his foul-smelling trap before he dumped the bucket's contents over her.
The officer had come to investigate a disturbance, on September 29, 2021, where 30 to 40 prisoners were banging and chanting, DevonLive reported.
It was then she heard her name called and she turned as Guest, 32, launched his trap and got the faeces and vomit on the officer’s face and in her mouth.
He denied being motivated by a grudge but did confess the guard was ‘not on my Christmas card list’.
Guest pleaded guilty to administering a noxious substance with intent but claimed that he had dumped rotting carrots, potatoes and other food scraps on her.
But at a fact-finding hearing held at Exeter Crown Court led by Judge Anna Richardson ruled it did indeed contain vomit and faeces - but not urine.
For his crime, Guest was handed another 32 months to run alongside his current sentence being served at HMP Dartmoor.
The court heard a statement from senior staff at the prison who described it as a "cowardly" attack on a hard-working prison officer that will stay with the victim throughout her career.
Guest's actions, known as 'potting', were partly responsible for an increase in disorder at the jail.
He said he threw the bucket because he wanted a transfer from the prison. His actions could have had serious health implications for the victim.
No analysis of the contents was made so the judge had to rule on the evidence she heard in court.
The victim said some went in her mouth. Mr Gregory Gordon, defending, asked the victim whether she could identify urine.
She replied she did not know what it tasted like but guessed it was similar to the 'bitter' taste she experienced.
The victim confirmed the contents of the bucket were runny.
"Thinner than tomato soup?", asked Mr Gordon. "Yes, more like chicken soup with lumps in it," she replied. "I was not able to identify anything in particular as I was in shock," she said.
She confirmed it smelled strongly of sick and she had to pick matter from her eyelashes in the shower.
Judge Richardson said she had no reason to doubt the honest evidence given by the victim and four witnesses and there was no evidence the bucket only contained dirty water and food.
