A man from Daventry has been jailed after he was found guilty of sexually assaulting a vulnerable man.
53 year old Jason Mustoe, of The Medway, was sentenced to three years and four months in prison, which was extended by a further two years on licence due to him being a dangerous offender.
He was also made subject of a four-year restraining order preventing him from contacting his victim as well as being issued with an indefinite Sexual Harm Prevention Order.
Mustoe was found guilty of one count of sexual assault on a male in January of this year.
The court heard that in July 2024, Mustoe had sexually touched the vulnerable man, who he had befriended, and when told to stop, continued knowing that his actions were unwanted.
The victim told Mustoe that his inappropriate behaviour made him feel uncomfortable, but despite apologising, Mustoe continued to make sexual advances towards the younger male, who made his excuses and left.
Once he was safe, the victim spoke to a friend who encourage him to report it to the police. Mustoe was then arrested and charged.
Investigating officer Detective Constable Stevens, of the CID West team, said: “Jason Mustoe’s predatory behaviour towards a vulnerable man, who trusted him and saw him as a friend, is deplorable.
“I am pleased that the jury saw him for the dangerous sexual predator that he is, and that the extended prison sentence reflects the seriousness of his offending and the potential risk that he poses to the public.
“Finally, I would like to commend the survivor for both his bravery and dignity throughout the investigation and during the trial, when he was forced to relive the traumatic experience due to Mustoe failing to take responsibility for his appalling actions.”
