Three men who used a stun gun on a pregnant shop worker and her colleague during an armed robbery have been jailed.

Steven Modeste, 37, James Irvine, 54, and Anthony Kimber, 43, attacked pregnant Jacqui Young and her manager Alexandra McMurray at the Original Factory Shop in Kelso, Borders, on October 5 last year.

The High Court in Edinburgh heard how the trio entered the store on Bowmont Street wearing balaclavas and discharged a stun gun at the two shop workers.

Ms Young, who was 14 weeks pregnant at the time, told the court she felt a "sharp pain" on her upper arm and heard a "zapping" sound.

The 31-year-old then kicked one of the men in the groin before she was dragged across the shop floor and into the office where the safe was kept.

Ms McMurray, 35, said she was "Tasered" during the incident and was so scared by what was happening that she played dead.

She said: "I could see electricity between two prongs. I heard Jacqui Young say 'get off'. I saw three sets of feet. Jacqui was in the middle. She was getting frogmarched."

The court heard that the gang got away with four days' worth of takings, the proceeds of a charity collection and "staff incentive money" totalling an estimated £7300.

Afterwards, Ms Young was taken by ambulance to Borders General Hospital for a scan on her unborn child.

Despite denying their involvement, the court heard the three men left behind enough DNA clues for police to charge them.

Officers who saw Modeste and Irvine at a house about 17 miles away in Galashiels said they appeared "panicked" when they came to arrest them and were holding bundles of banknotes that they were trying to hide.

Police found other material including tags, envelopes and paper with the Original Factory Shop logo.

A stun gun was recovered from behind the washing machine at the house in Kirkbrae, Galashiels, along with cash.

After a trial lasting 11 days, the men were jailed for a total of 26 and a half years after the jury returned guilty verdicts on charges of armed robbery, illegally possessing a stun gun and attempting to pervert the course of justice.

Following conviction, it emerged all three men had previous convictions for robbery.

Passing sentence, judge Lady Carmichael said: "All three of you have been convicted of serious offences - the most serious one was the robbery in charge two.

"It involved not just the threat of violence. What marks it out is the actual use of a stun gun on two women.

"This assault was particularly distressing as it led to concerns for her unborn child.

Modeste was jailed for eight years, Irvine sentenced to nine and a half years and Kimber was handed a nine-year sentence. All three were described as prisoners of HMP Edinburgh.
