Killers and rapists are among hundreds of foreign criminals who have disappeared while waiting to be deported from the UK.
Shock figures reveal that the Home Office have lost track of many offenders who instead of being locked up were allowed to roam the streets while facing removal.
One MP called the figures horrifying saying it was proof that the UK was a soft touch.
According to figures obtained by the Press Association, 450 foreign national offenders (FNOs) absconded in two and a half years to the end of June.
Although some were later located, the whereabouts of at least 234 are still unknown.
Conservative MP Tim Loughton, who is a member of the Commons Home Affairs Committee, said: These are very concerning figures and confirm a worrying trend that we are a soft touch when it comes to dealing with foreign national offenders.
It is a mystery to me why we do not immediately deport these criminals, some of them highly dangerous, back to their country of origin, and let their authorities deal with them.
The fact that these people are escaping the watchful eye of the Home Office and are back on our streets is horrifying.
Innocent people going about their daily lives could be at risk.
Offenders convicted of murder, manslaughter, rape, kidnap, weapons possession, robbery, conspiracy to defraud, theft, burglary and death by dangerous driving are among those unaccounted for.
If there is no immediate prospect of deportation or removal, foreign national offenders (FNOs) who have completed their sentence can be managed in the community.
However they are required to report to officials at set times and can be subject to bail conditions and electronic monitoring.
Offenders are recorded as having absconded if their whereabouts are unknown and all procedures to re-establish contact have failed.
Figures obtained under Freedom of Information rules show 251 FNOs absconded in 2016, followed by 164 last year and 35 in the first six months of this year.
As of the end of June, 223 male FNOs had not been found.
On top of that, 11 females who absconded in 2016, plus an unspecified numbers of five or fewer who absconded in 2017 and January to June this year, were also yet to be tracked down.
The Home Office said some of the absconders recorded as unfound in June may have been traced since.
A report from the immigration watchdog last year, flagged up shortcomings in arrangements for keeping track of foreign criminals living in the community.
It found offenders can fail to attend meetings with staff on as many as 19 occasions before the alarm is raised, while planned removals were often frustrated by last-minute legal challenges.
A third of planned removals of criminals failed – 7,772 out of 24,289 dating back to 2014-15.
A Home Office spokeswoman said: We always seek to deport those who commit crimes and whose conduct poses a serious threat to the basic fundamentals of society.
We never give up trying to locate absconders, which is why we have introduced measures in the Immigration Act 2016 that will mean that in the future all non-detained foreign nationals subject to deportation proceedings or a deportation order will be considered for electronic monitoring.
We have removed more than 44,500 foreign national offenders since 2010, and this week, like every week, more than 100 foreign criminals will be removed from the UK.
