Splitting up offenders between the public and private sector according to risk threatens public protection.
Offenders are generally not a compliant, problem free, group of people. They disproportionately suffer from mental illness, are four times more likely than the general population to misuse drugs and are 10 times more likely to have been in care.
They need to be supervised by experienced staff who can motivate them and properly assess risk.
More than 50 cases have been pulled together by the National Association of Probation Officers (Napo) after it approached members from across the country to provide examples of "complicated" medium risk sex offenders.
Among the offenders who would be transferred to the private sector under Justice Secretary Chris Grayling's shake-up of rehabilitation, are a 32-year-old repeat offender in Greater Manchester who was convicted for violence against a child.
The dossier includes cases of child abuse, harassment by the internet, intent to cause grievous bodily harm, unlawful wounding and instances of repeated domestic violence.
Some 2,300 sex offenders will be among the criminals whose supervision is outsourced to private contractors under government reforms to probation, it was claimed.
Around 3,200 gang members, 8,400 people convicted of domestic violence and 15,900 robbery cases are also among the "medium risk" offenders set for private supervision, the National Association of Probation Officers (Napo) said.
The public will be put at risk if such offenders are taken out of the care of the public sector and transferred to private firms such as G4S and Serco, the union said.
Speaking yesterday, Napo general secretary Harry Fletcher said: "The Government's plans are both chaotic and dangerous."
