A prisoner who filmed himself having sex with a prison officer and shared the footage on Snapchat has had his sentence increased following a Court of Appeal decision. The case involves an inmate identified in reports as Declan Winkless, who recorded sexual activity with a prison guard who is described as 18 years old. According to the accounts, the inmate later leaked the material online via Snapchat. The appeal is reported to have resulted in a higher sentence than the one originally imposed, with the Court of Appeal allowing an increase after the challenge was successful. The reporting across outlets focuses on the recording and dissemination of the sexual content, rather than other disputed facts in the case, and presents the sentence increase as the outcome of the appellate process. No additional details of the length of the new or original sentence are included in the provided summaries. The incident is treated in all sources as involving both the breach of conduct between inmate and staff and the subsequent online distribution of the footage.
