Day release from prison is to be scaled back following a series of serious crimes committed by offenders temporarily out of jail, such as Hertfordshire murderer Ian McLoughlin.
McLoughlin murdered Graham Buck in the village of Little Gaddesden in July last year while on day release from prison.
Now tighter rules about who is eligible for the scheme are to be introduced, while prisoners will only be allowed out for a specific purpose, such as gaining work experience, the Ministry of Justice said.
Day-release prisoners will also have to wear electronic tags, once technology is made available, the department added.
McLoughlin, who had killed twice before, was sentenced to a whole-life order.
It will no longer be considered an automatic right which is given when inmates are deemed suitable for open conditions.
There will also be a more thorough assessment of risks before temporary release is authorised.
