The man who murdered three small children and impaled them on ­railings has been cleared for release by the Parole Board.

David McGreavy, 67, beat to death Samantha Urry, nine months, strangled her brother Paul, four, and cut the throat of sister Dawn, two in 1973.

He was later sentenced to life in prison, with a minimum of 20 years after admitting all three murders.

But in an echo of the John Worboys scandal, a three-member Parole Board says he is no longer a “significant risk”, according to The Sun.

In the case of McGreavy, dubbed the Monster of Worcester and the Friday The 13th Killer, the board has said he should be freed from a closed prison.

He has been eligible for parole for 25 years but every previous application has been turned down. The last refusal was in 2016.

But last month the Parole Board ruled McGreavy had “changed considerably” during 45 years in jail and no longer posed a “significant risk to the public”.

A summary of its decision had to be disclosed to The Sun.

The panel said it had found McGreavy had “developed self-control”, and took “full responsibility” for his crimes. It also said he had a “considerable understanding of the problems he has had and what caused them”.
