A total of 91 prisoners have been accidentally freed by mistake earlier this year as the Government faces mounting pressure over the error.
The data, released by the Ministry of Justice on Tuesday, shows the accidental releases took place between April 1 and October 31 this year.
It comes as two other men were accidentally let out of HMP Wandsworth last week.
Brahim Kaddour-Cherif, a 24-year-old Algerian man, was found in Islington and arrested last week, following a tip off from the member of the public after they recognised him from a Metro newspaper.
Just a few days after he was released, William ‘Billy’ Smith was also accidentally freed from HMP Wandsworth.

A few days later Smith voluntarily handed himself back in.
The accidental releases happened just days after migrant sex offender Hadush Kebatu was mistakenly released from HMP Chelmsford in Essex.
Kebatu, a former asylum seeker from Ethiopia, became one of the most notorious sex offenders in the country when his case sparked protests outside the Bell Hotel in Epping.

Justice Secretary David Lammy previously said he was ‘appalled at the rate of releases in error’.
But prison guards have revealed to Metro this mistake is so much more common than the public realise.
They said most prisons are ‘overcrowded but understaffed’ meaning it is hard to spot such serious errors.
One officer told Metro: ‘It is a category B jail, there will be prisoners going in and out everyday for court dates and visits, and they are so understaffed.’
‘It is just part of a wider issue of prison funding.’
