A thug who brutally assaulted a Dumbarton pensioner in her own home has been jailed for eight years.

Kevin McCallum left frail 85-year-old dementia sufferer Barbara Slaven with three bleeds on her brain and horrific bruising to her face following the 2am attack.

McCallum, 42, robbed the pensioner in her Hawthornhill Road home during a 30-minute raid which saw him beat the defenceless elderly woman before ransacking her home looking for valuables to steal.

Following her ordeal, in the early hours of Sunday, April 14, 2019, Barbara was rushed to the Royal Alexandra Hospital in Paisley where she was treated for serious head and facial injuries.

Police got straight to work on the case, and raided McCallum's home with a warrant just a week after the cowardly attack on Barbara.

Officers found items including jewellery, a parasol and a thimble belonging to the OAP in his pad and he was duly arrested.

McCallum was then handed an early Christmas present on December 19 last year when he was convicted of robbery and assault.

He had claimed during his trial that Barbara could have sustained her injures "falling out of bed" - a claim the jury didn't buy.

The court was also told McCallum has a staggering 58 previous convictions for violence, dishonesty, possession of a bladed weapon and housebreaking.

He had been released from jail just two months before the brutal attack.

Today (THU) he was back in the dock at the High court in Glasgow where he was handed an eight-year jail term, with a further three years on licence when he gets out from behind bars.

Following McCallum's sentencing, Barbara's family asked police to issue the photo of her injuries to show what McCallum did to her.

Detective Constable Iain Allison, of Clydebank Police Station, said: "This was a despicable act carried out on one of the most vulnerable people in our society who suffers from dementia and was completely helpless to McCallum's actions.

"I would like to thank our colleagues in forensic services who worked tirelessly to analyse DNA samples in a short time frame to enable us to build a case against Kevin McCallum. I would also like to thank the local community for providing us with information.

"Barbara's family asked us to use this photograph of Barbara's injuries to highlight what happened her. I hope the conviction and sentencing will provide some comfort to Barbara and her family."
