A 15-year-old boy who raped and tried to rape a 65-year-old man after taking the party drug MCat has been locked up indefinitely for the public protection.
Ben O'Neill of Beck Crescent, Mansfield, pleaded guilty to robbing a 24-year-old man and two charges of theft and raping and attempting to rape and committing a serious sexual offence at an earlier hearing at Nottingham Crown Court.
Nottingham Crown Court heard that O'Neill was high on MCat when he was involved in a robbery with a second man who had been walking on a pathway on the old site of Sherwood Colliery, which is now a nature reserve.
It was 9.15pm on August 3 that he had been walking along when he heard shouting and laughing from a large group of people.
A male voice shouted and then two men from the group ran towards him and shouted 'Oi mate' and the man had turned to see what they wanted.
The unidentified attacker struck him with a bottle on his head, while O'Neill grabbed him in a bear hug.
The victim was hit and dragged to the floor and was left unconscious.
When he regained consciousness he realised his mobile phone and door keys were missing and he went home and raised the alarm he went to the King's Mill Hospital with non life-threatening injuries.
The next day O'Neill stole a bottle of vodka from a supermarket in Mansfield Woodhouse.
An hour and a half later he attacked the 65-year-old man, who was disabled.
He approached him carrying the bottle of vodka, he told the pensioner they were going to have some fun together and manhandled him into a nearby field.
The man could not refuse because of the condition he suffered from.
O'Neill said to him 'You're going to come and have sex with me' and forced him to the floor and slapped him and said he would have to perform a sex act on him.
The man said he felt physically sick when a serious sexual assault was performed on him.
After the attack O'Neill told the man to remain seated in the field for ten minutes.
When the pensioner dared to get up after five minutes, O'Neill shouted at him to get back on the floor.
The terrified pensioner remained there for the full ten minutes before going home and reporting the horrific incident to police.
Then the teenager went to a friend's house, knocked on the door, and was drinking from a bottle of alcohol and 'effectively took over', the court heard.
At the house O'Neill used a computer and when he left he took it with him - the second charge of theft he admitted to during his two day offending spree.
The court heard he had previous convictions for low-level public disorder and violence, burglary from a house and possession of an offensive weapon.
Andrew Langdale, said in mitigation that he had had "an horrendous upbringing in many ways" and an unsettled childhood.
He said that O'Neill had been a victim of an attack when he was a one-year-old.
When he was 13 he was diagnosed with ADHD (attention deficit hyperactivity disorder) and was on medication for the condition.
But when the party drug MCat - a plant food - found its way the area where he lived, he began taking it, the court heard.
O'Neill had also been smoking cannabis and drinking.
Sentencing him to a minimum jail term of three and a half years, Judge John Milmo QC said he was satisfied that the offences represented a 'deliberate attempt to degrade and humiliate a vulnerable victim'.
O'Neill will only be released when he is deemed to no longer pose a risk to the public, and he can only apply for parole after the end of his minimum term.
