Freddie Pritchard was locked up for two years after illegal intercourse with a teenage girl having previously breached court orders, then later started a blaze in his Main Street home.
The 29-year-old was added to the sex offenders register for 10 years after admitting kissing the girl, removing her clothing and having sex with her while she was too young to consent.
He had a previous order revoked, after receiving a four-year prison sentence at the High Court in December for the deliberate fire, with the new jail term to run concurrently.
When the case called in his absence, with Pritchard remaining in the cells, defence solicitor John Gallagher said he had “explained what was likely to happen”.
Sheriff Mhairi MacTaggart said she had “lived and breathed this case” and revoked his previous community payback order.
Pritchard was given a two-year prison sentence to run alongside his High Court punishment – and is now subject to police notification requirements as a sex offender for the next decade.
The offender was previously jailed for sending threatening emails to the girl and a letter to her family after having illegal intercourse with the girl when she was in her early teens.
He was ordered to serve 22 weeks behind bars after admitting causing fear and alarm to the girl between May 2021 and January 2023.
A social worker present in court suggested Pritchard was “quite unique in his degree of manipulation”, adding, “we don’t believe everything he tells us”.
Sheriff MacTaggart said she had “very significant concerns” about the offender and told Pritchard: “I have to deal with the cases in front of me – the very serious original indictment and the community payback order you breached.
“The young woman was sent some of the worst messages I have seen, it must have been extremely distressing. There was a degree of forethought and a degree of planning.”
She deferred sentence on the other charge to a later date, telling Pritchard the prospect of another prison term would “hang over his head” and a non-harassment order was imposed barring any contact with the girl until 2028.
Pritchard had been living at the council flat in Main Street having been freed from prison on March 1, 2024, with the High Court hearing he had taken “no action” to alert his neighbours to what had happened.
A probe later concluded the fire was deliberate and the High Court heard Pritchard admitted to witnesses he had used a cigarette to start the blaze, but had “not expected it to take hold the way it had”.
South Ayrshire Council estimated the repair bill to be between £25,000-£30,000.
Lord Young said: “You took no steps to inform other residents of the fire. Whilst the fire service was dealing with the consequences of your actions, you were seen laughing and joking.
“You show no real insight into your own actions. You are now 29 and you have not grown out of your criminal conduct – you have a short but concerning criminal record.
“The charge to which you have pleaded guilty to is such that the imposition of a substantial custodial sentence is inevitable.”
