Former PC Isaque Rodrigues-Leite, based in the Roads and Transport Policing Command, was sentenced at Croydon Crown Court to two years and three months’ imprisonment.
He was previously convicted at the same court of four counts of false imprisonment, two counts of assault, one count of coercive and controlling behaviour and one count of criminal damage.
PC Rodrigues-Leite carried out the offences between 2016 and 2019 where he repeatedly used threats and intimidation against a woman he knew.
The woman contacted police in September 2020 and he was arrested.
He was suspended from duty while the investigation took place and was dismissed from the Met at a misconduct hearing held in December.
Detective Superintendent Christina Jessah, from the Roads & Transport Policing Unit, said: “The nature of this officer’s offending was abhorrent. We do not want people who commit such offences working in the Met and our professional standards investigators will continue to be relentless in their pursuit of officers who let down their colleagues and Londoners.”
