Two criminals have gone on the run from an open prison - meaning four have fled from the same facility in just five days.
Convicted robber Marcus Brotherson, 27, and 24-year-old Jordan Hall, who was jailed for grievous bodily harm, disappeared overnight last night from HMP Sudbury in Derbyshire.
Two nights earlier Michael Fien McCarthy absconded from the prison. The 24-year-old was sentenced to three years for wounding with intent last year.
On Monday Andrew David Hudson, 38, who has convictions for burglary and robbery, disappeared from HM Sudbury.
Figures obtained from police by the Press Association reveal that a total of 28 prisoners are currently missing from the Category D jail.
This includes a number who have a history of violence, while one is still on the run from the facility more than 20 years after being allowed out in 1992.
The revelations come amid controversy over open prisons after a spate of inmates went on the run.
In the most high-profile case Michael Wheatley, who is known as "Skullcracker", carried out a raid on a building society while on the run from HMP Standford Hill in Kent.
Brotherson was described by police as black, 5ft 5ins tall and of a stocky build. He has short cropped brown hair, brown eyes.
Hall is described as white, 6ft tall and of a slim build, with brown eyes and cropped brown hair.
Their last known addresses were in Birmingham. It is not clear whether they left the prison together.
Glyn Travis, spokesman for the Prison Officers' Association, said: "Our view is the level of absconds doesn't surprise us.
"This is another example of how the system is broken and needs fixing. We keep telling ministers that they've been sending the wrong type of prisoner to open conditions for years."
Shadow Justice Secretary Sadiq Khan said: "The number one priority is catching these men as a matter of urgency.
"After the recent surge of escapes on his watch, (Justice Secretary) Chris Grayling claimed he'd put a stop to incidents like this, but still serious and violent criminals are going on the run on a worryingly regular basis.
"David Cameron's incompetent Government is putting public safety at risk. Corners are being cut, with prisons closed and prison officer numbers slashed.
"The wrong kinds of prisoners are being shoved into open jails. Warm words of reassurance won't keep the public safe - David Cameron needs to wake up, get a grip and put an end to the recent spate of absconds."
Last week it emerged that 88 prisoners are missing from Ford Open Prison in West Sussex.
