The hearing was held by City of London Police, where Steel had transferred to in 2022 before resigning a couple of years later.
Adedeji, who waived her right to anonymity, reported his behaviour to the Independent Office for Police Conduct in November 2023 and described the process from start to finish as “the biggest fight of my life”.
The panel heard that she first met Steel in June 2016, when she was 22 and out with friends in Shoreditch. He was 38 at the time and on duty as a plain-clothes officer.
It heard he claimed to be “Danny Stevens”, an undercover officer with no family.
Their relationship continued sporadically until it ended in 2021, during which he met her on multiple occasions while on duty.
Steel originally denied a number of claims, including sexual activity in an alleyway.
All allegations against him were proven, and he has now been placed on the police barred list, preventing him from returning to policing.
