AN ARMED robber who sprayed Alloa Post Office workers in the face with ammonia has died in jail.

Graham Wise, 42, was sentenced to six years and four months in jail after leaving a female employee blinded in one eye and her colleague with blurred vision after the attack in 2019.

During Wise’s sentencing at the High Court in Edinburgh last year, the court heard the woman has now regained the central vision in her right eye after specialist treatment but still has some peripheral blurring.

Her colleague who was also sprayed with ammonia was treated by paramedics after the attack at the Post Office in Mill Road, Alloa which netted Wise a mail bag.

Advocate depute Jane Farquharson QC said during the sentencing that before the raid on the Alloa Post Office, Wise went into the premises and asked what time it closed, before leaving.

He returned later wearing a beanie hat and, with a scarf partially covering his face, shouted to an employee: "Give me the f*****g money."

Miss Farquharson said: "She initially believed his comment to be a prank and laughed this off.

"However, the accused repeated the comment and they sprayed her in the face with a substance from a lemon-shaped squeezy bottle.

"The substance caused her eyes to sting and blurred her vision.

"The accused then sprayed [her colleague] with the same substance, which mostly struck his chest but also splashed the side of his face and eyes, causing his vision to become partially blurred."

The employees managed to get out while Wise climbed over a counter and later ran off with the mail bag.

Miss Farquharson added: "[The woman] had a burning sensation in her right eye and had lost the vision in her right eye."

Two days after the assault and robbery Wise struck again at the Riverside Mini Market in Abbey Road, Stirling, which houses a post office and shop.

Wise menaced an employee there with a knife before robbing her of £794.

He was sentenced to more than six years in jail for his crimes, however the Scottish Prison Service have confirmed he died last week.

The cause of death is unknown but a fatal accident inquiry will be held.

A statement from the Scottish Prison Service said: "Graham Wise, 42, a prisoner from HMP Shotts, has died on September 23, 2021.

“He was convicted at the High Court in Edinburgh in 2020.

"Police Scotland have been advised and the matter reported to the procurator fiscal.

“A fatal accident inquiry will be held in due course."
