Paddington Green Police Station

From the longer Wikipedia page

Paddington Green Police Station was a Police Station located in Paddington, central London, England. The station was operated by the Metropolitan Police Service, but it closed in 2018. It also served as the most important high-security station in the United Kingdom. This is because prisoners suspected of terrorism were held at the station for questioning. The building was a typical 1960s office block, but underneath the station were sixteen cells located below ground level, which had a separate custody suite from the building's other cells. Building work was completed in 1971.
