Recent revelations expose the absurdity of prisoners mistakenly set free, including one individual who remained at large for a staggering 579 days.

An official investigation has uncovered further alarming errors, where released inmates went on to commit additional crimes due to these oversights.

The inquiry particularly examined the erroneous release of sex offender Hadush Kebatu from HMP Chelmsford last October.

The findings detail numerous oversights leading to the premature release of Kebatu, a small boat migrant, after serving only a month of a 12-month sentence for sexually assaulting a 14-year-old girl and a woman in Epping, Essex.

These crimes occurred while Kebatu was housed at the Bell Hotel in the town, funded by taxpayers, which ignited a wave of anti-immigration demonstrations.

Justice Secretary David Lammy faced significant backlash regarding his management of the Kebatu incident and similar prisoner release errors.

The new report, by former National Crime Agency boss Dame Lynne Owens, found there were a series of unsatisfactory decisions in Kebatu’s case, as well as human error and shortcomings in technology and prison policies.

Dame Lynne also revealed a string of other cases for the first time.

Justice Secretary and Deputy Prime Minister David Lammy was castigated in November for his handling of the fiasco involving prisoners being freed early by mistake 

Ethiopian sex offender Hadush Kebatu was released by mistake in October, sparking a row over Labour’s record on law and order

One unnamed prisoner was wrongly freed from HMP Altcourse, in Liverpool, due to a ‘breakdown in information flow’ when his release date was being calculated. 

‘The offender who was originally sentenced for theft, burglary with intent to steal, and driving while disqualified was released in error and remained unlawfully at large for 579 days during which time a further offence was committed,’ the report said.

In other cases, a freed criminal was unlawfully at large for 255 days, during which time they committed an additional offence, and other was on the run for 230 days.

Dame Lynne also highlighted the case of a man sentenced for robbery, conspiracy to commit robbery, and handling stolen goods who was wrongly released in December 2024.

The prison failed to spot he was serving time for multiple convictions and he remained free for 174 days.

During that period he committed a new offence of possession of a firearm with intent to endanger life.

In another case, a pair of co-defendants, who were father and son with the same name, were ‘mixed up by the prison due to the prison not identifying the correct date of birth on bail paperwork sent by the court’.

The son was supposed to be released but HMP Elmley, in Kent, freed the father instead.

‘The bail paperwork referenced the date of birth of the son … however, this was missed by the prison and so they ended up releasing the father,’ the report said.

The unnamed father – who was sentenced for robbery and burglary – was at large for five days.

In October last year a defendant awaiting trial for ‘sending communication threatening death or serious harm’ was mistakenly freed from HMP Peterborough after a court clerk logged incorrect bail details. He was at large for 40 days.

Dame Lynne made 33 recommendations to improve the way prison releases are handled.

Mr Lammy accepted all 33 ‘in principle’ and announced an £82million package to ‘crack down on mistaken releases’, including moves to ditch archaic paper-based records.

It will include a ‘single digital identity for every person who enters the prison system’ in a bid to avoid misidentification of inmates and track them through the system.

Data from the Ministry of Justice, published today, showed 179 prisoners were freed by mistake in England and Wales in the year to March, down from 262 in the previous 12 months but still higher than the 115 seen in the year before that.

Mr Lammy pledged to ‘cut release mistakes to as close to zero as possible’. 

‘This independent review makes clear the unacceptable rise in release in errors have resulted from a broken system caused by 14 years of underinvestment and overcrowding in our prisons and courts,’ he said.

‘Today we are taking action to bring the prison system into the 21st century.’

Epping sex attack victim, 14, learned of early prison release mistake on social media 

The schoolgirl victim of Epping sex offender Hadush Kebatu learned from a social media post that he had been freed, hours before being she was formally notified by the authorities.

Dame Lynne Owens’ report said the 14-year-old, known as ‘Victim A’, and a woman who was also sexually assaulted by the Ethiopian migrant were not informed until hours after the blunder.

Hadush Kebatu, pictured in a grey prison-issue tracksuit, was filmed by a member of the public in Chelmsford city centre hours after being mistakenly freed from jail. His 14-year-old victim learned of the Prison Service’s mistake on social media hours before being formally notified

‘By that point, social media reporting had already reached at least one of the victim,’ the report said.

Kebatu was freed from HMP Chelmsford at 10.35am on October 24 last year.

That lunchtime he was filmed by a member of the public as he asked for directions in Chelmsford city centre – with clips posted online – and Kebatu boarded a train to London at 12.42pm.

Essex Police contacted Victim A’s mother to alert them of the mistake at 5.04pm.

It added: ‘The father of Victim A suggested that Victim A was sent and watched a video on social media of Mr Kebatu out in the community before contact was made with them by the prison or by the police.’

Dame Lynne’s report said Kebatu’s release had ‘a profound and detrimental impact on both the victim and her family’.

‘They described the experience as ‘retraumatising’.

‘Victim A’s father described the fear he had knowing that Mr Kebatu, on mistaken release, could have re-encountered his daughter and what could have occurred,’ it said.

Dame Lynne found there is ‘no formal policy’ on contacting victims when a release in error takes place.

She recommended the Ministry of Justice and Home Office ‘urgently’ speak with victims’ groups to ‘developing a clear policy’, including when and how victims are notified.

Kebatu was eventually arrested in north London after a three-day manhunt. He was deported.
