Detective Constable Dariusz Alexander, attached to the Roads and Transport Policing Command (RTPC), was found to have breached the standards of professional behaviour in relation to discreditable conduct.
An allegation of breaching the standards of professional behaviour in relation to authority, respect and courtesy was not proven.
DC Alexander was previously found guilty of outraging public decency following a trial at Stratford Magistrates’ Court on Thursday, 22 June.
On Saturday, 18 March, two Met officers were carrying out enquiries relating to an incident which had occurred on Hampstead Heath several days earlier.
As they did so, they saw a man – later identified as DC Alexander – exposing himself. He was arrested and charged and later suspended from duty.
The allegations were found proven and they were so serious as to justify dismissal.
Detective Superintendent Christina Jessah, in charge of RTPC, said: “Everyone in this organisation knows the high standards expected of them and it is right that those who fall short are held to account.”
