A triple killer won £800 compensation after some personal items were lost and damaged when he was transferred to Woodhill Prison.
Kevan Thakrar, 26, from Stevenage, Hertfordshire, who is serving three life sentences for killing drug dealers, received the payout for damage to his stereo, alarm clock and nasal clippers.
Items lost included cranberry juice, protein powder and toiletries.
District Judge Neil Hickman said there had been a “cavalier disregard for Mr Thakrar’s rights and his property”.
In March 2010, Thakrar maimed three guards at Frankland Prison in County Durham after stabbing them with a broken bottle, but was cleared of two counts of attempted murder and three of wounding with intent.
Following the attack, Thakrar was moved from Frankland to Woodhill Prison and it was during this move that some of his possessions went missing.
Judge Hickman awarded him a further £500 to compensate him for lost photographs and personal items, making £814.97 in total.
The prison ombudsman had originally offered Thakrar £10 in compensation, but he took the case to court last year and Judge Hickman ruled that he deserved a further payout.
Peter McParlin, national chairman of the POA, The Professional Trades Union for Prison, Correctional and Secure Psychiatric Workers, said: “It’s a ridiculous award, it’s a disproportionate award.
“This is a high-security prisoner – as a bare minimum it will be costing the taxpayer at least £50,000 a year to be kept incarcerated.
“He’s the architect of his own situation and we are in despair.”
A Prison Service spokeswoman said: “We robustly defend all cases as far as the evidence allows.”
After the judgement, Thakrar boasted about it on his Facebook page saying he hoped to send bailiffs to the Ministry of Justice to ensure they paid his compensation.
