Description (written by the developer; not a statement by this register)
Welcome to HMP Thameside — a UK-based, Serco-operated Category B prison roleplay. We offer realistic prison operations, structured staff ranks, inmate systems, training sessions, patrols, and incident responses. Join us to experience professional and immersive prison RP: security, inmate management, control rooms, escorts, CCTV operations, and more. We value discipline, professionalism, and realism. Apply for staff roles or join as an inmate to start your sentence. This group is NOT officially affiliated with Serco or the UK Government. It is purely for Roblox roleplay.

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
