Forty per cent of inmates at a West Lothian prison told inspectors they had been abused, threatened, bullied or assaulted by staff, prompting safety fears.
HM Inspectorate of Prisons for Scotland (HMIPS) visited HMP Addiewell in November last year and released a report on its findings on Thursday, raising significant concerns about the "enduring challenges" impacting the safety and security of the facility.
During the visit, inspectors found 40 per cent of prisoners said they had been subjected to abuse, threatening behaviour, bullying or assault by staff, with 60 per cent claiming they had witnessed this behaviour towards other prisoners.
