Julian Maylor and Reiss Comrie, both 24 at the time, were cleared of killing Michael Hennessy in Lindholme Prison, Doncaster, in December 2013, by a jury at Sheffield Crown Court in August 2014.
The number of deaths per year in UK prisons rose from 198 to 257 from 2010 to 2015, according to figures released by the Ministry of Justice earlier this year.
A total of 291 individuals are accused of 278 offences in South Yorkshire’s prisons and young offenders centres from August 2013 to August 2016.
Senior Lecturer in Criminology at Sheffield Hallam University, Dr Jamie Irving, said these recorded offences are likely to account for a small proportion of actual crimes committed.
“Much like any officially recorded crime, the ‘dark figure’ of the bottom of the iceberg that sits below the water line is much greater.”
Most alleged offences in South Yorkshire’s prisons related to possessing or smuggling in prohibited items.
There were 96 accusations of smuggling prohibited articles into or out of prison and 83 accusations of possessing such items making up 61.5 per cent of the total accusations.
It is illegal to convey items such as drugs, explosives, firearms, alcohol, mobile phones, cameras, tobacco, money, clothing, food, letters and tools to prisoners.
Thirty accusations involved possessing, supplying, misusing or possessing with intent to supply illegal drugs such as cocaine and heroin.
South Yorkshire Police have been contacted for comment.
The percentage of positive results from random mandatory drugs tests across the UK has increased in the last year according to recent government figures.
Mandatory testing for New Psychoactive Substances is the latest step in the government’s strategy to eradicate the use of drugs across the prison estate.
Anyone found in possession of these substances in prisons can face up to two more years behind bars.
Dr Irving said that prohibiting items increases the amount of underhand trading in the ‘prison economy’.
“Banning items of concern to the authorities can simply increase a potential ‘stock-list’.
He also said that when prisoners trade they put themselves in danger.
“Fights, bullying and victimisation in prison occurs as the prison economy of traded contraband goods thrives and a credit system is in place, increasing the likelihood of debt.
“Inability to repay prison debts are punished harshly.”
Dr Irving believes the government and prison authorities should focus on rehabilitating prisoners instead of ‘backward thinking and knee-jerk, media-driven policy-making’ to prohibit and punish them.
“Offering prisoners meaningful activities to occupy their time allows a more strengths-based positive approach to be taken towards enhancing the rehabilitative effect that prison should support.”
A spokesperson from the Ministry of Justice’s Prison Service said: “We have a zero tolerance approach to drugs and violence in our prisons.
“Safety in prisons is a vital part of our reform plans and offenders caught with prohibited items could face extra time behind bars.”
Justice Secretary Liz Truss announced this week that an additional £14m would be invested to increase staffing levels by over 400 prison officers by March 2017.
