A £5000 reward is being offered to trace a man who attacked and robbed a pensioner in her South Lanarkshire home.

The 87-year-old victim died in hospital two months after the "terrifying ordeal" at her house in Townhill Road, Hamilton, on September 3.

Police said she answered her door at around 7pm to a man who forced his way in, assaulted her and made off with a three-figure sum of cash from her purse.

The woman, who was knocked to the floor, was unable to get up and was found the next day by her son.

She was admitted to Hairmyres Hospital for treatment where she remained until her death on November 4.

Police have now revised their description of the suspect, who was initially thought to be aged between 50 and 60.

Officers are now looking for a man aged between 20 and 40, of average build, with a local Lanarkshire accent. He was wearing a dark hooded top at the time.

Although the woman's death is being treated as unexplained, a dedicated inquiry team has been set up to establish the circumstances surrounding the robbery and whether or not her death is connected to the incident.

Detective chief inspector Raymond Brown said: "Extensive enquiries have and continue to be carried out to gather as much information about this incident as possible.

"However, despite previous media appeals and door-to-door enquiries in the local area, we still need information from the local community to help us provide answers for the victim's family.

"Someone forced his way into an elderly lady's home and subjected her to a terrifying and traumatic ordeal and it is absolutely critical that we find this person as soon as possible."

He added: "I am confident that the answers lie in the local community and it is very possible that the person responsible has confided in a partner, friend or someone close to them.

"Anyone with information is asked to contact officers at the dedicated incident room based in Livingston by calling 07917803807 or 101.

"Crimestoppers is also offering a reward of up to £5000 for any information leading to the arrest and conviction of the person responsible for this robbery.

"The charity can be contacted on 0800 555 111 and all calls will be treated in confidence."
