Two inmates have been found dead at HMP Liverpool in the space of three days.
Daniel Rowland had been on remand over a £280 robbery
Staff at the prison in Walton found 42-year-old Patrick Bailey in his cell on Saturday.
It followed the death last week of remand prisoner Daniel Rowland, 31, who was due in court the following day accused of robbery.
Bailey was three years into a five-year sentence for indecent assault. Investigations are taking place into both deaths.
He was found by staff hanging in his cell at 1614 BST. Despite efforts to resuscitate him by paramedics, he was pronounced dead at 1635 BST.
A Home Office spokeswoman told BBC News: "Every death in custody is a tragedy and our thoughts are with the family and friends of Mr Bailey."
Daniel Rowland had been on remand over a £280 robbery at the Netto supermarket in St Mary's Road in Garston, Liverpool.
The Chief Inspector of Prisons, Ann Owers, has expressed concern about a series of suicides in prisons in England and Wales.
Twelve inmates have taken their lives in the past 12 days throughout the country.
