Royal Navy submariner who groped colleague at Faslane jailed for sex attacks

A Royal Navy submariner who groped a colleague at Faslane while on bail for another sexual assault has been jailed for two years.

Jack Seviour, 25, attacked the woman at accommodation at the naval base in Helensburgh on March 23, 2023.

Seviour also committed sex attacks on two other women between January 2022 and February 2023.

He was claimed to have recorded one of the attacks on his mobile and later described his actions as ‘rapey’.

Seviour was able to carry on working for the Royal Navy despite being bailed for one of the attacks before striking again at Faslane.

Seviour was found guilty at Glasgow Sheriff Court of three sexual assaults.

Sheriff Louise Arrol KC imposed a three-year extended sentence upon Seviour.

He will be under supervision for one year upon completing his two-year prison term.

The sheriff said: “It is clear that the impact of these crimes against your victims have had varying degrees of profound effect, and I commend them for giving their evidence.

“You had a positive upbringing – some might say a privileged – as you had employment and a family network.

“I have heard submissions about an alternative to custody, however, I am satisfied that the nature of two of the charges and the impact on the victims at the time passes the custodial threshold.

“I consider that the period of licence will not be sufficient to protect the public from serious harm – so your sentence will be in two parts.”

Seviour was also put on the sex offenders register for ten years.

The court earlier heard that Seviour, of Plymouth, Devon, had been a weapons engineer submariner for five years.

Seviour and his colleague were at an afterparty in the building where he stayed on site when the attack took place.

A friend who saw the woman the next day described her as “sobbing” when she recounted what had happened to her.

The trial was told of an earlier incident when Seviour met a woman from dating app Tinder at her student accommodation in Glasgow’s Townhead.

The pair had sex, but Seviour carried out sex acts that she did not consent to.

Jurors heard how Seviour slapped her face three or four times and she told him no.

A third woman told the court that she had also met Seviour on Tinder and went to her student accommodation also in Townhead.

She claimed that Seviour assaulted her during consensual sex.

Seviour claimed to jurors that his victims’ evidence had been “fabricated” and all three women had lied.

Iain Smith, defending, told the sentencing that his client has since lost his job and relationship as a result of the conviction.

The advocate added: “His point of view is that the offences were committed against a background of taking alcohol and binge drinking which he is adamant on changing.”
