A jail inmate has been ordered to serve an extra six years in jail for a slasher attack on a fellow prisoner who he accused of being a snitch.

Tommy Burton left victim Lee Dainter needing five stitches to two cuts on his face and permanently scarred after the attack at Channings Wood Prison near Newton Abbot.

Burton went on to carry out two disgusting attacks on female prison officers in which he threw or squirted a toxic and evil substance smelling of faeces and urine in their faces.

He was serving a 30-month sentence for burglary when he carried out the slashing attack in Devon and the so-called ’potting’ attacks in Bullingdon Prison, Bicester, and Portland Prison in Dorset.

Burton, aged 36, formerly of Navigator Close, Hilperton, near Trowbridge and the Salvation Army hostel at Swindon, admitted wounding with intent and two offences of administering a noxious substance.

He was jailed for a total of six years four months by Recorder Miss Hannah Willcocks at Exeter Crown Court. The new sentence will follow his existing term.

The judge told him: ‘You used weapons to injure and humiliate. Prisons are places which have an enhanced need for good order and where there is the potential for acts of violence to cause further disorder.

‘The two potting offences were carried out on two separate occasions and while you were under investigating for the earlier assault.

‘They were truly repellent, premeditated and designed to humiliate. They used improvised weapons and were carried out against those who were serving the public. That is peculiarly subversive of good order.’

Mr Gordon Richings, prosecuting, said the attack on Mr Dainter happened as he was carrying his evening meal back to his cell at Channings Wood on March 13 last year.

He heard someone come up behind him and was hit from behind twice. The first blow caused a one-centimetre wound on his eyebrow. The second left a five-centimetre cut down the side of his nose.

Mr Dainter did not know Burton well but heard him call him a snitch. Officers took him to hospital where he needed five stitches.

He made a victim impact statement saying he is reminded of the attack every time he looks in the mirror and is self conscious about his scar, which he fears will damage his prospects of working in the hospitality industry after his release.

The two other attacks, known in prison slang as pottings, happened at Bullingdon on November 30 last year and Portland on February 5 this year.

The first victim had a jug of foul-smelling liquid poured over her head as she supervised a mealtime and was witnessed by 190 inmates.

Her hair was covered in faeces. She was so disgusted that she had to take time off work and to doubt whether to carry on her career as a prison officer.

Burton attacked the second female officer with a squeezy bottle full of a similar mixture and needed hospital treatment to remove it from her eyes and nose.

Mr Robert Ross, defending, said Burton’s prior offending arose from his using drugs to cope with memories of an abusive childhood in care.

He carried out the attacks in prison as a result of pressure from gang members who required him to do their dirty work for them.

He has now stopped taking drugs and hopes to live a normal life when he finishes his sentence.
