A paedophile pensioner who terrorised schoolgirls for nearly 20 years failed in a bid to be released from prison early - because he still poses such a risk to children.
Disgraced teacher William Wright, 81, was jailed last year for repeatedly sexually abusing female students at a top Scottish school.
The former Eastwood High School music teacher launched a bid for freedom, asking to be allowed to serve the remainder of his sentence at home.
He hoped to be released on a Home Detention Curfew, which sees offenders fitted with electronic tags, but the Parole Board for Scotland blocked the move.
And we can now reveal the reasons the authorities chose to keep Wright, of Elderslie, Renfrewshire, behind bars.
A letter sent to victims, seen by the Daily Record , reveals why experts ruled it was not safe to release Wright into the community.
The letter blasts Wright, who is serving a four-year sentence, as an unrepentant sex offender who has "a deviant sexual preference".
And it said he failed to engage with social workers trying to help him change his ways, making it "impossible" to monitor him properly when released.
The letter states: "The offender did not accept responsibility for their offences or that there was anything about their behaviour which led to their convictions.
"They therefore considered that they did not pose a risk of harm to children and did not need to change. The Board disagreed.
"The offender lacked insight into the risk they presented and took no personal responsibility for the harm done to their victims.
"Little to nothing was known about their pathways to offending, making it impossible for social work to formulate an adequately tailored community facing risk management plan."
The letter also states that both social workers inside and outside of prison felt it best for Wright to remain locked up.
It adds: "Neither prison-based nor community-based social work recommended release as the offence was unable to engage with them, show insight or take any responsibility for why they found themselves the subject of a long-term sentence for sexual offending against children.
"Due to this intransigence, offence-focused work would be limited.
"The offender was assessed as having a deviant sexual preference, had not carried out offence-focused work and was unable to participate in programme work due to their limited insight.
"It was the view of the Board that their risk was not currently manageable [in the community].
"That the offender was able to follow prison rules did not persuade the Board that their risk was safely manageable in the community, because there are no potential victims in custody."
The letter, issued in February, ends by saying that there should be another review next February.

In 2018, Wright was jailed for abusing some former pupils at the school, in the affluent Glasgow suburb of Newton Mearns, prompting other ex-students to come forward to police.
Last year he went on trial at Paisley Sheriff Court charged with abusing three women when they were teenagers.
One of the other women was the first witness, telling the court Wright abused her more than 100 times in her first year of secondary school.
The jury was told she'd been abused by Wright more than a thousand times in total whilst she was at the high school.
After her testimony, Wright struck a plea deal with prosecutors to plead guilty to charges in relation to her and was jailed for the offences.
