A man convicted of two murders in Australia and once branded "the most dangerous man in Australia" cannot be deported back there, despite having violently attacked a woman while in the UK. The case has raised questions about why the justice and immigration systems have been unable to remove a convicted double killer from British soil, even after further violent offending here.

Details of the specific legal or procedural barriers preventing his removal, along with the exact nature of the UK attack, were not included in the available article text. The story forms part of wider Daily Mail coverage of crime and justice issues, including separate reporting on prisoner release schemes and extradition cases.
