A Devon and Cornwall Police officer - who failed to arrest a man found in possession of crack cocaine - has been given a final written warning.
It follows an investigation by the Independent Office for Police Conduct into a stop and search.
The incident was referred by the force in November 2017 after others raised concerns.
A hearing found the police constable had committed gross misconduct for failing to arrest the man for a drugs offence.
The officer had the grounds to arrest the suspect for a drugs offence but chose not to. The officer’s improper conduct and failure to appropriately handle and log evidence meant the man could not be subsequently prosecuted for any offence relating to the drugs found on him. His actions compromised the integrity of the investigation and also put his colleagues in a difficult position.”
A referral was also made to the Crown Prosecution Service as there was an indication a criminal offence may have been committed. The CPS decided not to authorise any charge.
