British police have been asked to review the case of an Irish prisoner who was found hanged at Wormwood Scrubs prison in London ten years ago.
John Boyle (27), a native of Donegal, had been held in a segregation block at the west London jail when he was found hanging in his cell in 1994.
Lawyers for Mr Boyle's family have written to detectives urging them to review the matter again.
The Boyle family's solicitor, Mr Daniel Machover, appealed to an anonymous caller who contacted his office in 1999 with information about the case to come forward again but he said no fresh police inquiry was expected without new evidence.
A Prison Service spokesman said the service would "fully co-operate" if police decided to reopen the investigation.
An investigation into staff brutality at the jail in the late 1990s led to the suspension of 27 prison officers and the convictions of six for assault.
It had been claimed some prisoners were subjected to sustained beatings, mock executions and death threats.
Following the conclusion of the criminal cases in 2001, inmates at the jail brought a number of civil cases against the Prison Service. The last of those was settled in December last year.
The prison service has paid out a total of £1.7 million sterling in compensation to prisoners who alleged mistreatment on the part of prison officers. Although it denied liability in all the cases, the prison service accepted there were "failings" among some officers.
